Don't all good stories start with the characters hating each other a little bit? Regardless, early in the trip is when most minor slights like rude comments would be made and that would be Druuk at his most level headed. He understands he has to share a space with these people for a few weeks. Towards the end of the trip though maybe he just fights some nobody NPC after they bump into each other.

As for relationships, Druuk wouldn't really approach anyone on the ship. Don't worry, that doesn't mean it'll be difficult getting him into whatever the main thrust of the RP will be. I assume there will be some job posting and we all take it for our own reasons and work together that way.

The other easy in is if Kraseawei [@Expendable] approaches him and they become friendly. Druuk would recognize she's not exactly a fighter but her strength lies in finesse, something he is sorely lacking. From there he would stick with her and whoever she may choose to ally with.
