It seems that smiling has no place here. The seriousness of the topic is clear from the look on her face once her polite pleasantness fades completely. She waits for him to choose his words and explain, in detail, where his thoughts are. It's better like this. It allows her to understand him more thoroughly, and that is something she appreciates immensely.

Once he's finished, she nods, accepting his answer while giving it the respect it deserves. "I appreciate that more than words can express."

The silence sits in the room for a minute, and Lieselotte sets her glass on a table. "Isidor is one of the most powerful, most talented martial casters I have ever known. But even she needs someone to look out for her as she looks out for her brother." She folds her hands in front of her and turns to look Harrowheart in the eye. "We are a fiercely loyal people. What we receive, we return in equal measure. Everything you have said assures me that Isidor and Viatorus were right about you. They both regard you very highly, and I believe so shall I. If there is ever anything you need, or want, for any reason, for them or your own family, tell me. I would be glad to help."
