TJ does live at the dorms (he has to!) but he's off at his apartment sometimes on the weekends, and on breaks (and he's posted an invite to a big New Year's bash on his journal). TJ is happy to keep Kieran on track for studying. And will try not to get distracted (he may well try to convert Kieran to the musical theatre side of things *laughs*).
Jackson has been realizing that basketball is pretty much a solitary thing for him at Presley! But music... oh yeah... he's totally passionate about it. If he's not composing, he might be singing under his breath, fretting on an invisible guitar, chording piano work on a table... and he has a bad habit of setting everything he needs to memorize to tunes so he can pass tests (unless Ben helps him get things nailed into his brain). Jackson's great at math/languages/music but rather helpless at memorization, especially history. But he's almost always doing something with music.
