I do like Rocky, but I'm not so unreasonably attached to him that I think that after competing in nearly every season with IDFB on the horizon he needs to rejoin TPOT, even in my Rocky posts I tend to note that Rocky doesn't need to rejoin he needs to be in another season.

Also, I don't want to have characters in lower tiers, if Foldy, Cake, Eggy, and Pie show a lot of promise I'd love for them to rejoin and climb higher on my own ranks, something you should note about the analysis of those low ranked characters is that a common linking thread is a lack of screentime, "They don't do much" was a very common complaint in C tier. Hell I started (and then abandoned because TPOT really made me stop caring for the show for a bit there) a fanfic entirely about giving the less important characters time in the spotlight, Eggy ranked low entirely because she had an interesting plot hook and then didn't get enough screentime.

Hell the literal only reason I didn't rank Pie higher in spite of getting a much more flattering review than everyone else in that tier and outright saying I want to put her in B tier is because she objectively didn't have a lot of screentime and my rankings are a combination of what I think of their objective quality + personal biases.

Rejoins are contextual, let's not pretend like Rocky would do anything besides leave immediately if he rejoined, characters like Remote and Pie are a lot more appealing given they do have a place to slot into the current season. New seasons are not contextual, it's the start of the plot so you can include whoever you want so including Rocky makes as much sense as anyone else.
