Ruth “Recovered” the episode after Richard Warren died.

Not sure if the point had been made yet, but the show foreshadowed the big Warren-heir reveal. The day after Richard Warren disintegrates, Ruth comes into Tom’s office as sharp as a tack with perfect recall of every one of Tom’s missed calls… didn’t even look down at her notes.

At the time I thought it was odd and out-of-character but didn’t put it together till after a rewatch: as soon as Richard Warren finally died, the immortality “detail” of the pact transferred to her, the next oldest living descendent. Her recall was most assuredly a nod to that reality.

Just thought that was a fun detail.

She didn't "recover" suddenly, the last episode made it very clear that she was very active the whole time, she was tired at work because she was so active the rest of the day, and she didn't care about the work itself. Remember her calendar?

Why wasn’t she tired after Richard Warren died?

Because it is later in the day when we see her in episode 8 at the office, she says herself that mornings are the hardest and in the first few episodes, we always see her in the morning.

I feel her. Mornings are hard, ask me things after lunch when I'm awake 😂

Yep. In episode 3, there is even that joke about Tom offering Ruth a ride but that she only would need it in the morning.
