Yeah, I laughed out loud at that one and totally distracted my wife's enjoyment of the moment. Win some, lose some.

Thing is though, did Barrowman flub the line? The way he said it, it doesn't make that much sense grammatically.
Felicity going all den mother on Ollie and Dig was fun - as was her trying in vain to disguise having Holt look into Martouf's tattoo thing without springing the worst kept secret hero team on the planet aside from Team Flash.

Holt should have had more of a denouement though instead of just disappearing - what was he doing, telling his also-gay uncle in Brooklyn all about it?
And it was good to see that the new arrow cave was in fact under the Palmer building instead of just some random place (or wherever Oliver's oft-seen backup hideout was). However, we saw concept art earlier of a wicked-awesome new lair previously, and this certainly isn't it. Did the cancel out of that?
And as for the flashbacks, I'm guessing he won't be island-bound for too long. After all, at SOME point he still has to be a Captain in the Russian mafia and presumably re-engage with Zelenka at that point.
