[The silence makes her wary, hesitant, and Ochako roots herself to the ground, not daring to move closer until she's sure this isn't one of Trench's tricks. It'd be real easy to do, to play with her mind and emotions like that, and it's happened too many times to count. Even after he finally speaks, she chews her bottom lip, fighting back the maddening urge to go closer that gnaws at the back of her head. What she wouldn't give for a sense of home again. She feels safe with her friends, and with Bakugou, of course, but... There's just something a little different when she's holding onto an adult. Maybe she really is still just a kid, after all.

The caution is mirrored back at him despite hoe eager she is to rush over and wrap her arms around him tight, even if it is Aizawa and not someone more personable like Mic, or even All Might. Taking a deep breath, she tries to will a smile on her face, but it comes up a little short.]

It's...really good to see you too, sensei. I missed you so, so much. [So much that her nails dig into her palms from how tight she's holding the arms of that bag.] Of course I'll tell you all you need to know, but...I'm sorry, it's just how this world is - it's very cruel. I have to be sure you're really you somehow. Sorry...

[But she can't jeopardize herself so easily. There are people here that would be really upset if something happened to her again.]
