It was complicated but interesting. To know that there were other worlds out there were fascinating, and she knew Armin would love it if he could be here. She hoped, maybe one day, Armin could see all of this because he deserved it. Out of all of them, Armin deserved to see a better world.
She did smile softly and reached out to touch her new friend's hand briefly. "Then I'd take care of him. Even if you might not get along with him completely, if you love him, then...I'd take care of him." She blushed a bit then, looking away as if the intimacy was a bit too close for comfort, even just the talk of it.
At the mention of her good friends, Mikasa smiled again and kept looking down. One hand gently brushed the red scarf against her neck. "I do have some good friends, yes. Eren...I'm probably closest to Eren." The faintest blush crossed her cheeks. "He's more athletic, a pretty good fighter, too. He's saved my life twice now, and probably will more in the future. Armin sounds like your friend Lesley. Armin...well, he's a genius, I think. He always wanted to go outside the walls and to explore the world around us."
