I think Liz is going to remain a tougher Liz, but she retains much of who she has always been. She always cycles around to her familiar position of accusing Red of not caring about her at all, but only using her or only helping her in order to get some thing that he wants. A couple episodes back she found out that Tom's killers had been after some "item" of Red's. And she accused Red of only helping her find them because he wants to get it back. (Liz assumed that Tom's killers still had the item). Frankly I get sick of her adopting that position over and over again. How many times and how many ways has Red risked his own life to save hers, or just to be near her? Liz's history is one of periodically assuming the worst about Red and telling him she will only work with him on th blacklist but wants nothing else to do with him. I think that trope is way over done in this show.
