hc_bingo April Challenge

I didn't feel up to managing to get my hc_bingo March rec list done in time, although I did collect enough recs that I'll have to do a belated one before Amnesty ends. But I signed up for April in a spirit of optimism anyway and got this strip:

branding

crisis of faith

estrangement

extortion

The challenge is to write a crossover using any (or all) of the prompts I choose. I've no ideas as yet, but I do like the strip. What fandoms should I use??
