I did try to give Shess a smile, but she looked weird, so I kept her a bit bewildered looking. Issie looks like she's trying to be friendly and Shess looks like 'so, you're big now, that's weird'.

I don't know if this will be useful to you, or maybe just entertaining, but there's a behind the scenes video of Michael Fassbender working with black bears for A Bear Named Winnie. It's here (https://www.youtube.com/watch?v=W-kaiCd4EU8). It's not all him, but it might help you see how a black bear and human might interacting with each other.
