Lavellan is eager to take any affection Solas offers her--it feels new and giddy, and there's a small worry that she's acting like a teenager with her first paramour. Though--that's basically what he is, isn't it? Though she has a certain dignity she expects herself to maintain.

"You would survive and you would manage, as you always have." She says it with a sense of certainty. "I expect you would wander around doing a great deal of frowning, with a crease in your brow, right here." This is accompanied by a poke right between his eyebrows, which is followed with a kiss, to soothe. "But I am glad that I can offer you some comfort. As handsome as you are when you frown, I think you rather more so when you smile."

She's trying to distract. To make light of a situation that she can't imagine, couldn't begin to. Maybe in the act of losing her arm, had she come close to being akin to a mage without magic. Quite nearly made Tranquil. But she's hoping that he'll smile, instead of worry.
