[Bolin grins as he listens to Opal. He's actually almost giving her a sappy grin as she talks about her keeping up with pro-bending and, more importantly, how hard she's been working to increase her bending skills. He can't help but flash a smile of pride, knowing that his girlfriend is doing well.]

That's so great! And especially Considering that it hasn't been long since you started training with Korra and Tenzin! I told you that you were a natural from the beginning! [Well, he probably very much did, though it's not like he would have really known... or knew all that much about airbending despite seeing Korra do it all the time.] I'd love it to come over one of these days and watch you train and see how you're doing. Even if Tenzin probably wouldn't approve of the distraction.

[He jokes a bit, but for the most part, he's trying to keep things lighthearted since he is more than a little nervous. Even if Opal has told him time and again that she actually likes his normal self and doesn't like it when he tries to go out of his way to impress him, it's still so hard to do that.]

So... other than having the day off, what were you up to in the city today? I mean, before I ran into you.
