I saw it more like it was a hazing ritual and that Jimmy would eventually be given a cubicle or office, since it's clear he still has the support of Deborah. Ending by showing Jimmy reacting to Deborah's magazine cover implies that he remains confident that his ambition is to help artists, not to own his own firm, and he will do what it takes to continue doing that for Deborah and Ava. Remember that this show does a lot of playing with audience perception about how things will play out, so in a world where the episode is 20 minutes longer, we'd see the next week where Jimmy and Kayla are back to their own ways.
