In VisionQuest, Tommy Shepherd displays super-speed and vibrations that can affect objects and let him pass through matter. His link to Vision comes from Tommy Maximoff, one of the twins magically created by Wanda in WandaVision, whose consciousness finds another life in Thomas Shepherd's body. By episode 4, the show depicts emerging abilities, not a fully trained Speed with every power known from the comics.
Warning: spoilers for VisionQuest episodes 2, 3 and 4 and the ending of Agatha All Along follow. Reporting cutoff: October 22, 2026.
Why does Tommy have two sets of memories, and why is Vision his father?
In WandaVision, Wanda Maximoff creates a family life inside Westview with Vision and the twins Billy and Tommy. When that magical reality ends, so does that version of their family. Agatha All Along resumes the brothers' story: Billy, now connected to William Kaplan's life, searches for Tommy's consciousness and, guided by Agatha, finds a drowning boy who can become its new host. The brothers are not reunited in that scene.
In VisionQuest episode 3, Thomas tells Vision that other youngsters held him underwater in a pool. As he felt himself dying, he sensed another presence filling the space. Since then he has carried recollections of his own childhood alongside memories of a family including Wanda, Vision and Billy. His account and the earlier scene in Agatha All Along establish the connection, but do not establish that every memory or aspect of the original boy's personality was erased.
The Vision traveling with Thomas is the rebuilt version seen after WandaVision. His doubts about fatherhood are central to the drama: the relationship has an emotional and magical history, not a conventional biological parentage established by laboratory proof. Disney officially describes Thomas as a boy who may be Vision's reincarnated son.
Power by power: what do episodes 2, 3 and 4 actually show?
This comparison distinguishes events covered by identifiable episode recaps, Thomas's own account, and powers associated with Speed in comics. A suggested ability should not be mistaken for one he can already use at will on television.
| Episode | Shown or reported on screen | What the evidence supports | Comic-book comparison |
|---|---|---|---|
| 2, Theseus | On a custody transport, a guard's electrical weapon discharges back toward him; Tommy vibrates and helps force open the vehicle's exit. | An involuntary response and vibration affecting the surroundings; the exact electrical mechanism is unexplained. | Speed manipulates matter through acceleration and vibration, including in an escape-from-custody story. |
| 2, Theseus | During the rescue at Saint Mabyn's, his hands move abnormally fast as he attempts to open a lock. | Super-speed emerging under stress, without precise control. | Super-speed is Speed's central ability, echoing his speedster relative Quicksilver. |
| 3, Reboot | Thomas's hand partially phases into a vending machine's glass, and he is injured when he loses control. | On-screen vibrational intangibility, but unstable. | The comic-book Speed can also vibrate through solid material. |
| 3, Reboot | Thomas recalls his body vibrating and the pool water becoming very hot during his near-drowning. | A description of his origin, not a fresh present-day display of deliberate control. | Hyperkinetic vibrations can alter and destabilize matter in the comics. |
| 3, Reboot | At a hotel pool, Tommy uses speed and vibration to supply the energy needed to restart Vision's core. | A directed use of his powers to save someone, aided by Vision's instructions. | This is a story-specific solution in the show, not automatically an established comic-book feat. |
| 4, Malware | At a gala, Thomas accelerates to pull Katerina Wells away from an attack. | A visible super-speed rescue. | Fast movement is consistent with Speed's role as a speedster hero. |
Are super-speed, vibration and phasing different powers?
Within VisionQuest's fictional rules, Thomas's extreme speed enables unusual vibrational frequencies. That links the effects on doors and glass to the energy created at the pool. This is not teleportation: the vending-machine sequence depicts partial passage through matter, with loss of control and injury.
There is a difference between altering matter and deliberately triggering explosions. Comic-book Speed can accelerate and destabilize material destructively. The first four episodes do not demonstrate that his TV counterpart has mastered remote molecular explosions. They also establish no precise top speed in miles or kilometres per hour, or general immunity to electricity.
How are Tommy, Billy and the Young Avengers connected?
Billy Maximoff and Tommy Maximoff are twins within Wanda's magically created family. Agatha All Along follows Billy and links his brother's fate to the drowning boy; VisionQuest gives Thomas Shepherd his identity, memories and powers. The productions are narratively connected, but the brothers have no on-screen reunion in the episodes 2 through 4 considered here.
In the comics, the young men reappear as Billy Kaplan, Wiccan, and Thomas Shepherd, Speed. Both belong to the Young Avengers. Marvel's reading guide includes Young Avengers (2005) #10 in its Wiccan and Speed selections. That helps explain the institutional escape parallel, but does not confirm the show will reproduce that issue's events or establish a new TV team.
What remains unresolved after episode 4?
Tommy has displayed rapid movement, vibrations and momentary intangibility, but still shifts between involuntary effects and controlled efforts. His maximum capabilities, mastery of molecular explosions and any reunion with Billy are not demonstrated or conclusively resolved by this point. Calling Vision his father is a question of memory, recognition and kinship, not proof of ordinary biological parentage.
What should you watch and read to understand Tommy?
For the screen continuity, the most helpful order is WandaVision, then Agatha All Along, then VisionQuest through episode 4. For comics, Marvel's official list points to Vision and the Scarlet Witch (1985) #12 and the Young Avengers (2005) run, particularly issue #10. The two continuities share ideas but do not recreate the same plot scene for scene.
