"Usually anybody who's a person can learn magic. There's a couple of exceptions - some people don't have souls, and that'd prevent it, but Alex would know if you didn't have a soul."
"Definitely a soul in there," Alex nods.
"There you go." They reach the final room. Sandy knocks. "Jack, Gav, get out here, we're all going to dinner with Alex's new roommate."
Two boys come out. One of them is identical to Kostas except for the color of his tongue stud (his is silver, Kostas' is gold). The other is shorter and stockier than the twins, and wears a slight frown.
"-oh, okay," the twin says in response to no apparent stimulus. "Hi, I'm Gavriil Manos, bearer of Hypnos, god of dreams. I'm a psychic and I manifest ectoplasm, which I can shape into various objects and effects.
"Are we introducing ourselves? I'm Jack Schmidt. I'm a shifter and a power mimic, if I touch someone I can use their powers for a few minutes. Are they doing the 'we're secretly greek gods' thing at you? You're going to make us all look like weird nerds, guys."
"Like you're not a weird nerd," Kostas says, rolling his eyes.
