Oh I didn't even bother right after the film. I believe my post at the time said "I don't even know what to do with myself" and it was 100% literal and accurate. But by time #2 a couple weeks later with goshawk I could actually start imagining, say, Jyn clocking Han in the jaw over the part where he totally screwed up a job she was doing before she ended up in jail.

I mostly handwave the mechanism. It's not real, it's just for my own enjoyment.
