[Her nerves are fraying. What Illya is asking of her and what Lisa is agreeing to do are not quite the same, and she hasn't processed that fine distinction yet. So she's starting to panic, trying to work out what she's going to do, debating if she should ask someone for advice before the two of them go in, but she can't show that or she's going to lose what credibility she has with this poor girl-

-and then there are arms around her, and slowly, her panic ebbs away. She doesn't miss the words out of the girl's mouth, and Lisa starts to recognize that she's overthinking this, too. For all she'd been worried about Illya pushing herself too hard, clearly she hasn't internalized her own advice, and it's... a little humbling, and a little galling. Still, she's not going to leave Illya hanging, and her arms come around her friend in turn, tightly but not too tightly. Her tone, when she manages to speak, is quiet but warm, affection coming through clearly.]

Silly girl... of course I was going to come if you asked. You couldn't pay me to stay away. I... [She shakes her head, not trusting herself to laugh in case it comes out as a sob.] Thank you, Illya-chan. Thank you for trusting me.

[A small part of her is glad Illya remembered their promise from before, because boy, she was not in the headspace for it, and she appreciates the hell out of Illya's forwardness now.]
