ok so like- my theory is that, in the original image showing the 3 question marks on the lifesteal twitter, there was blue, red, and purple My theory is blue was for 4cvit, red was for jumper/minutetech and purple was for wemmbu, but due to last minute decisions, they decided to add jumper/minute
Minutetech replacing Wemmbu in season 5 would make sense, since he did change his skin to have wemmbu's tiara, and it would represent minutetech taking wemmbu's place.
