Felicity exclaims, not even attempting to reign in her surprise at a statement that's pretty much out of left field - though it was, she supposes, the same for Oliver too, when Barbara first told him. Closing the distance between them, she grabs his hand and tugs him over to the couch to sit with her. "Okay, tell me exactly what happened. She knows some...other version of you? How does she know you?" There's a couple of obvious options she can think of for why Barbara knows all about the Oliver Queen in her world and how he spends his nights, and Felicity's not sure she's thrilled about either of them.
