Hmm... Although the idea sounds appealing we're not exactly enacting a 100% accurate depiction of how life used to be like that. It'd probably be the most pleasant experience for everybody involved if we don't get down to details of writing in foreign languages. The occasional word like 'Hei, Hallo, ja or nee/ nein' would probably be okay, but I think it's better not to do more than that. It gives just that little bit extra, without distracting too much from the actual roleplay.
I could picture Baersun grabbing Lydia by the throat and lifting her up if she tries to protect him while he growls some words to her of how he doesn't need protection.
I like to play in partner's O/O's as well. Under normal conditions I wouldn't have my character be that forceful, but I think it'd fit in well and probably be something you'd 'enjoy' happening to your character too. It'd make sense in the roleplay as well, I think.
I'm really looking forward to start with this game, there is so much potential here for interesting scenes.
For now, however, -holds his furs open and invites Lydia for that cuddling they talked about, his heavy body tired from the training he endured.-
