Oh, and also ask them about their air consumption, and octo.
DSAXE01 had a good point about the equipment familiarity. Especially where the alternate air is included with the BCD inflator. Work out the OOA scenario so that you are both comfortable with how it would proceed. Try out the alternate air source while at surface or even better while on boat. Be familiar with how it works. As you will be new buddys, it won't hurt if you bump into each other some as you work at staying realtively close particularly if you are drift diving. Better than being too far apart.
