Brian was able to move in with his parents, but he has to pay them rent money. He has to work at this data/hardware store type thing (Let's be real - it looks like the Buy More from Chuck.)
Brian found out that Sands was the one who killed Rebecca's father. And Rebecca surprised him by showing up at his apartment demanding that he tells her everything he knows about Senator Morra.
Brian fled to Russia to help Piper get the last of the ingredients to make the enzyme on her own. Before that, Sands and Morra thought she was dead. Brian told them he killed her. But as we all know, she's alive.
Brian gets the info he needs in exchange for him to leave Russia immediately. The parallels between this scene (of him being taken on the truck ride and dumped) and the one later in the episode was really well realized.
He takes on cases and helps people out - either by sketching the suspects or getting more visits by the clones of his subconscious, worrying about him.
This episode starts right where the previous one left off. This show is really good about doing that. This episode also continues to feature the amazing friendship of Brian and Rebecca.
