6499 Alexis is the tempgfe Alexis now charging a hefty $100 tip for gfe and bbbj.
Jade/Chanel 3125 is also same Chanel at tempgfe same deal, also goes by Valerie at Spa540 - Chanel that is.
3638 is part of the blackberry bait and switch crew, running multiple names and ads. the Brazilian 3172 and 3638 Alexis are downtown, Coco/Cassidy is out closer to Burnaby. All 3 open to anal.
So two different Alexis, but the 3638 one probably won't be what youre expecting at the door, but I could be wrong. Just that this outfit along with the Kat/Ashanti outfit are notorious of bad bookings and bait and switches. So, there's your heads-up.
