Season 1, Episode 7 of Watson, titled “Teeth Marks,” pairs a medical case about a woman whose memory resets every three minutes with Moriarty’s return. The critics we could check gave it a positive reception, and the episode’s strongest case is that the two storylines push each other forward rather than competing for time. The sample is small, though: three critic reviews, and no audience scores or viewership figures for the episode.
What happens in “Teeth Marks”
Watson and his team help a woman whose memory resets every three minutes. While they work the case, Watson experiences auditory hallucinations and begins to wonder whether someone is behind his decline. Meanwhile, Moriarty plots his next move. That is the official premise from CBS and Paramount+. The synopsis does not describe the medical explanation for the memory resets or how the case is resolved, so this review does not speculate on either.

Two storylines in one hour
The episode runs on two engines, and it helps to look at each one separately before asking whether they work together.
The memory-reset case
The case is the episode’s immediate mystery. A woman’s memory restarts every three minutes, which gives the team a puzzle with a built-in clock. The synopsis confirms the premise and nothing more, so the strength of the case depends on how the episode handles that clock, a point only a viewer can judge after watching.
#1 Best Overall
- Movie dvd
Watson’s decline
Watson’s auditory hallucinations and his question about whether someone is causing his decline are the character thread. The synopsis puts these elements in the hour, but it does not establish whether they deepen Watson’s arc or divide attention from the patient story. That judgment belongs to the reviewer, and the critics below read it differently in emphasis, not in outcome.
Moriarty’s return
The official synopsis says only that Moriarty plots his next move. CBR’s Joshua M. Patton goes further, describing this as Moriarty’s first onscreen appearance since the series premiere, with Moriarty threatening Watson’s team while the patient case and Watson’s declining health complicate the hour. That is one critic’s account, not a production fact confirmed elsewhere. Even so, it explains why the return carries weight: it changes the stakes of a case that would otherwise be self-contained.
Rank #2
- Mario
Does the balance work?
The most useful question about this episode is whether the procedural and the serialized elements reinforce each other. Tell-Tale TV’s Caitlin Wyneken addresses that directly:
“The good news, at least, is that we’re moving in the right direction with the balance of episodic plots and ongoing character arcs.”
Rank #3
- Morris Chestnut
Collider’s Maggie Lovitt also reviewed the episode positively, though the listing does not show a numeric score for that review. Taken together, these critics read “Teeth Marks” as an hour where the case of the week and the larger danger are meant to feed one another, with Moriarty’s presence giving the patient story higher stakes and Watson’s decline giving the threat a personal edge.
My verdict: Moriarty’s return is worth the wait if you watched the earlier episodes for the ongoing threat, because this episode puts that threat in direct contact with the team and with Watson’s own unraveling. It is less clear that it will satisfy viewers who want a standalone mystery first, since the synopsis suggests the serialized plot is never far from the surface.

What this review cannot settle
- The episode’s scene-by-scene plot, including how the memory-reset case resolves.
- The medical explanation for the woman’s condition.
- Creator intent or production interviews about the episode.
- Viewership or audience reception figures, none of which were found for this episode.
Those gaps leave the verdict above resting on the official premise and three critic reviews, which is a modest base for a firm conclusion about the season.
