As Emily entered her room she saw that you had curled up on the bottom bunk where she had put her old stuffed cat from before she had you. Emily's roommate a vampire named Thaumalese, but preferred to go by Thaumy said "Little thing got a little tuckered out. The journey must've been stressful. What was it's name again?"
Emily sighed and said "She's Katherine, a her not an it." Emily went to her own desk and said "I guess I should do a little bit of studying on that magic stuff. At least some of the more basic stuff."
Thaumy asked "Aren't you humans terrible at magic? Why are you studying it?"
Emily said "Just a good idea to know the general foundations of how magic works... not like i'm gonna use Katherine as a familiar." She cracked open a text book and opened a bag of chips.
Thaumy said "Ah, we having our dinner then? Mind if I had mine here?"
Emily said "Sure... Those things were in cans or blood boxes and not plastic bottles or donation bags right?"
Thaumy produced a blood red box took out a red straw, plugged it in and said "yeah, you don't have to look at the blood directly." then took a long sip as the blood entered the vampires digestive tract. Life seemed to flow into her veins as her skin seemed to get some color into them, and her breasts seemed to perk up and grow a size. heck the girl's bum seemed to grow taught as well.

Thaumy chided "What are you into girls? What have you been doing to Kathy on lonely nights?"
Emily said "Don't make me fling my garlic chips at you." then took a bite before going back into her book. After an hour Emily yawned, brushed her teeth, and then picked you up, got under the covers, and dragged you into the bed with her. Your presence comforted her enough to let her sleep comfortably enough.
Thaumy on the other hand technically didn't need sleep so she started considering if she wanted to play a prank with the 6-8 hours of time you and Emily would be asleep. When you woke up...
