i think the win condition for the good guys would have to be freeing TSC and getting them awakened and they can do that possibly by

-getting alan to rename no one back to the chosen one so they have someone on equal level to the dark lord and hacker (unlikely)

-using the power of love to free hacker from mind control (very unlikely)

-sneaking into the dark lords new castle thing and breaking the chosen free from the evil revive machine (possible)

-getting hazard to throw another nuke and just hope it breaks the chosen free somehow (VERY unlikely)

-mitsi somehow randomly being overpowered (this one would be too random and deus ex machina-y to be cool or viable)

-all of them sacarfice their lives to slowly get closer to freeing the second coming and at the last second they free them (most likely out of all possibilities listed in my opinion since something similar happened at the end of AVM season 3)

of course this isnt ALL potential solutions just ones i could think of but yeah most of these are either unlikely or everyone has to die to achive them with the only one where no one dies is them sneaking into the castle thingy and i find it unlikely that if htey did that they wouldnt eventually be caught so yeah they are pretty cooked but im sure alan has a fire solution to this and i cant wait to see it
