Looking at the situation at the end of _IICY_, there is still a strong possibility of a relationship with Trent in Daria's future. Though Daria is going off to college, she is still going to be close friends with Jane, which means that she is likely to run into Trent from time to time. Daria is no longer underage, and she's actually had a boyfriend so she's less likely to assume that her boyfriend has to be perfect.
It's true that dating Tom hasn't exactly prepared her for the nature of most men. Tom is courteous almost to a fault, gentle, highly tolerant of Daria's eccentricities, and sexually undemanding. He's also intelligent and understands Daria's sense of humor. Compared to Tom, the vast majority of guys she would meet in college would impress her as crude and stupid, and repulse her with the speed of their advances.
This is actually a _good_ thing for Trent `shippers though, as it means that Daria is less likely to find a relationship with a college classmate which would preclude her involvement with Trent. And Trent's good points are ones which make him superior as a potential boyfriend from Daria's point of view: he is also courteous, gentle, and highly tolerant of eccentricities; we don't know how he deals with women he is attracted to, but he has never struck me as very sexually aggressive. Trent's _education_ is spotty, but his _intelligence_ is high; and after a semester of college, Daria might be very tired of over-educated idiots (she'll likely encounter more than a few at the lecterns).
I could easily see Daria winding up in a serious romantic relationship with Trent while she's at college (or when she's home for the summer).
What do you guys and gals think?
Sincerely Yours, Jordan
