[She can't say that she's not surprised by that. To think of her as a dear friend when they finally just met? Not that she's against that or anything.. And she seems very polite. It's no wonder Armin likes her from what she's heard.]

Oh well.. It's nothing really. I'm just... I'm sorry I couldn't have helped him during those trials he faced in the other world...

[Which she doesn't even have to guess what Mikasa means by that because she more than likely know exactly what she means.]

I'm glad to be able to meet you as well. I'm sure Armin is already on his way to get you. If he isn't already, I'll be sure to tell him you're here.
