Whenever weve seen him on screens, Professor Martin Stein has largely been the coolest cat in the room. So, based on that, it was massively WTF to see him have a breakdown of sorts during Pilot Part 2. Sure, meeting his younger self and having a come to Jesus moment was likely a lot to take in for Stein, but it still felt a little out of character. In fact, it would take the words of Jax to snap Stein out of his funk. What then followed was a little bit of a love-in as Stein talked about what a fine young man Jefferson is as viewers gave out a collective awwwww.
