Today's Fact
Verified against independent sources. Issues cited below.
Most founding X-Men simply stayed at the mansion and kept training. Jean Grey's parents wanted something more ordinary for their daughter: after she graduated from the school run by Professor Xavier, they enrolled her at Metro College, and in X-Men #24 (1966) she stepped down to part-time status with the team.
The arrangement split her life cleanly in two. On campus she was a college student with classes, books and a commute; on call she was still Marvel Girl, expected to drop everything when a mission needed a telekinetic. The comic treats the tug-of-war honestly — she missed full-time hero work even while her family pushed for a normal education.
Part-time never became permanent. Jean drifted back to full duty with the team, and the college experiment survives as a small, human footnote: the most powerful mind on the roster once tried to be a commuter student first and a superhero second.
Why It's Obscure
Between saving the world, the X-Men's telekinetic tried timetables, tuition and a part-time hero schedule at her parents' insistence.
