I'll only answer this one question Anon 174 (you), but remember you can't ask any questions like these. Next time you add a comment  on this blog, make sure it contributes to the speculation of Season 12.

The Reds and Blues joined forces in K.I.T. B.F.F., but they weren't friends and more like forced allies. However, by the time of Recreation, most of the Reds and Blues treated each other as neighbors instead of rivals and eventually friends. You can find more information about this on the Blood Gulch Crew article or the wikia itself if you look for it.
