There's nothing weird about finding troll urine among many things' ingredients, but some people are still squicked by it, and the first time you hear about it, it's not usually a nice surprise.
Panel 1: Myces is saying thanks because she aknowledges redoing her bandage was a nice thing, but she's unsure because of the hurting.
So...Troll urine in your food is normal. Even still, catching a Troll peeing into your mixing bowl is a little revolting.
I would rather not hire a Troll to work for me. No one in the office would drink the coffee, that's for sure.
There's grosser things in industrial food's ingredients already! XD
Haha! I love this scene. Pekka is like a grandfather figure to Myces. The cake bit is a funny way to show her innocence and his wisdom!
He does see her like his own grandchild. :)
