The episode will show Liz out of the hospital and walking with a cane, although it’s unknown exactly how much time has passed since Liz woke from the coma.
Even with her injury, one would think the F.B.I. would find a desk job for her to continue to contribute if she still wishes to.
Knowing that Liz is well enough to be out of the hospital in the midseason premiere makes the spin that she’s no longer involved with the F.B.I. taskforce all the more interesting.
We can probably safely say that the episode won’t entirely take place directly after she wakes, given the extent of her injuries even if she is up and about.
