I think the consieair was made/hired to keep the emotion lord in check. Sine the emotion lord has like ultimate power, he needs the consieair to be his babysitter. but when the emotion lord told Chris about his future, nothing happened to beth and they got together. This is not how the original timeline went. But with the emotion lord in a temporal pair-of-socks, he cant fix it so the consieair has to fix it. he recruited plum to help. His ultimate goal is to obviously to stop this dangerous man. Now this could be the emotion lord but i think it is beth's father. He is trying to bring the worm to the real world. In the original timeline, chris may have beaten the worm but beth had to sacrifice herself for chris to unlock his emotion lord powers. If they were to hook up, Chris would have sacrificed himself to save beth. They hook up and the world may end. (or maybe the dangerous man is Chris and his future self)
I posted that on "merewif tag." Now with this trailer and the last one, i want to add to this. With the end of the previous episode, we see the first time beth's dad me the worm. This may have grown quickly and the courageous battlers had to kill it sending it to the see through zone. The battlers soon get lost in the see through zone and you guys know the rest. Now with this preview, we see that the emotion lord possessed Catbug from the world of the pair-of-socks. He wants chris to change their future. Now since the consiear has changed his destiny were beth possibly dies, the emotion lord wants chris to put their destiny back on the track to beth. Saving his soul means he does not want to let beth die. Or at least thats what i think.
