I wonder why Jen didn't ask about the attack, what did they think they were doing. Clearly, she didn't find out they were trying to get her blood from him. I did notice Blonsky caught on to Jen's surprise quickly. Can't imagine why unless he knew Wrecker had attacked Jen. Also, what contact info to josh she had, they got her to delete it. On the other hand, it could be nothing.
Something I've seen others note is that Jen doesn't seem to be quite as quick on the uptake when she's Shulkie. Problem is, she's also drunk half the time when she's 'Just Jen,' which isn't helping as far as picking up clues.
