Alright, so I noticed a few differences with Queen and Elin.
Queen gives you a slight handjob as you finger her in the pool, if you had let her tease you in the pool previously. Not really sure if that's the reason or not though. Then there's the kissing scene at the end with her vs sucking her tits after Priscilla leaves and getting a handjob. Oh, and well Cass revealing that Queen was secretly meeting elves, though that's not really shocking. Those are just the few that pop out after I just finished my second playthrough.
For Elin, it was the teleporting again on the magic playthrough vs only her glowing on the table in the warrior one. I'll see if there's anything else a bit later.
I didn't get to say it earlier but Priscilla was as hot as believed. I know she's probably up to no good with who she's related to, but I don't really care. I almost feel bad for cock blocking Lockhart hard. Who am I kidding? Fuck him. I'm going to fuck his mom while also keeping Elin to myself.
