There's programmable lights if Felix wants to simulate a proper day cycle. Jim's shown him how to use them before. Has a note to himself even to make more use of them if he ever starts feeling worn down the way he did before the events of Altamid. Jim likes to think he's beyond needing such things out here but experience has proven that five years is quite a long time with no sense of normalcy for a human's biological instincts.

"Anything interesting?" What sort of practice? Probably not conjuration else Felix likely wouldn't have drifted off. Nor mentioned it to Jim in the first place however passingly. Tiber gets up and stretches out the way only a cat can, back legs and then front before he shakes out his fluffy golden head and hops down to go get into trouble poke around their quarters while Jim takes the empty seat at Felix's side.
