In number 37, Marten complains to Jimbo that he has thousands in student loans to pay off.
In #435, Marten's mom says her work paid for Marten's tuition.
It would violate the no-nitpicking rule to complain about this apparent inconsistency, but there's no rule against making up elaborate silly stories to "explain" it. Surely we can come up with something more interesting than the real explanation.
How about this: Marten's mom tried to game the system by having him take out student loans even though he didn't need them and then invest the proceeds. Unfortunately, the investment in Hillary Clinton porn flopped, leaving Marten on the hook to pay back the loans out of his meager income.
Or, Marten had his tuition covered, but even his mother's income couldn't cover the cost of textbooks, so he had to take out multi-kilobuck loans to finance them.
Or maybe it was peer pressure -- his fellow students surrounded him in a circle and said "All the COOL kids are taking out student loans".
Or Marten lied to his mother about the tuition to spare her feelings and allow her to believe she was covering his education while he sank into debt.
None of these are quite wacky enough. We need to get Pintsize into the story somehow.
