Love Me Like I'm Not Made of Stone

When meeting Felicity, Oliver has a flashback. Afterwards, he flees, leaving behind hiss 'latted' laptop. She further investigates on her own, but lurking underneath everything else is Felicity's concern for Oliver. Just like with anything that matters to her – she doesn't know why he matters but he does, she can't let the episode – what she fears to be PTSD – go.
