There was a split second shot of a very young (long haired) Oliver peeking around a corner into the office at Felicity--presumably we're supposed to think that Oliver had been in the building before the events of this series took place and saw her then? (Did *we* see that at some point? It's been a long time...)
So... did the comedian have an accent or not?
As for the kid's heart, it's much more likely she was misdiagnosed to start with than that it healed miraculously.
Leland in session with Beelzebub... no. I think I may be done with this.
