MC Sibling: What is this, the Dark Ages?

The Mage:

MC Sibling: You know what? Since you asked me, no, you can't. Beat me in a duel first.

The Mage: They would worry about the practical side of it. Are you covered enough from the elements?  What will you wear in battle?  They’d end up mothering the MC.

The Royal: They’d be fascinated with the tattoos.  If the MC was comfortable with showing them they’d like to see all of them.

Maeve: She’d be concerned about the first impressions the MC gave, which would lead to her recommending tailors and clothing just so it looks somewhat noble.

Alistair, The Healer, & Dorin: Varying degrees of “that’s hot. i’m horny now.”

Well there’s the stuff seen in-game, generally they are shy and uncertain about their role in Etrea.  

They also have a Champion, but their’s isn’t a mage.

If they are a male, then he was a surprise to your parents.

If they are a female, then she’s proven that she can be commanding, it just takes a lot to bring it out.
