As part of conversation when someone on tinder mentioned her specialization I mentioned that I'd just been talking to someone with that specializaiton (from OkCupid). I name-dropped the first name of the other person expecting that they wouldn't know each other- but the tinder girl did, and then asked if I've been on a date with the other woman already (no).

Can I still be asking them both out on dates if they know each other or what is my strategy here? What would you do?
