I think Sabine and Daniel could be interesting - maybe not necessarily as close friends, but people who understand each other/go out for a drink every once in awhile maybe? I'm not sure how she'd run into either of the wolves - she does occasionally go to Tooth + Nail, everyonce in a blue moon, so maybe a run in with Rhys there would work? She's always been a little confused by wolves in general, so any chance to learn more is a good one!
And yes yes, all the clients for August. He'd be very happy to meet Jesse XD (and also very excited to see where Elijah and August go, lawlz) And awesome, co-workers/boss would be awesome!
