There's a reason that certain characters don't come back. Trent was only a plot device/satellite in Action, not that his role in Island was much different, so there's nothing left to do with him in the writers eyes. Zeke fans wouldn't shut up about him coming back, so the writers didn't know what to do with him when they did put him in WT, so they just kept him as a joke character and made it even worse. Eva is the only one who has potential to develop, but her character is pretty one-note and best used for quick gags in Aftermaths and cameos.

But just because characters don't come back every season doesn't mean they're forgotten. It just means the writers don't have anything for them to do. Since WT, the only chance any of these characters (except Zeke) had was in TDRR, where there were three to four slots open with two underdogs from early seasons taking up half of them. If we get another season of TD or RR, we could possibly see them again, along with the likes of Katie, Sadie, and Dawn, who are the most requested characters according to Christine Thompson. It's just a waiting game at this point.
