Oliver and Thea in “Unfinished Business”

Oliver

You know, it's been a while since I've offered you a little big brother advice. Do you mind?

Thea

This should be good.

Oliver

When we find Roy. Not if, but when we find Roy, I think maybe you should go with him.

Thea

Where?

Oliver

Wherever he's going. I mean, um, Thea, I'd miss you like crazy, but you said you haven't been the same without him. So maybe you shouldn't be without him.

Thea

You really think I should go?

Oliver

I don't want you to go, obviously. But you've seen what having Felicity in my life has done for me. You deserve that same kind of happiness, Speedy, wherever it is.
