Okay, I've been thinking, if there was a Gravity Falls and Invader Zim crossover, we all know one thing: Zim would fall for Bill's stupid manipulation hook-line-and-sinker, immediately. However, would the possession thing even work, if that's the route Bill went down? because Zim's PAK latches onto the nearest life-form and practically just downloads his personality onto them, if Bill was attatched to Zim, would he be overwritten? If he chose to remove it, would he have to take it off, then put it back on every ten minutes and hope it doesn't finish overwriting him? Bill would find this SUPER annoying, and may even say "fuck this, this dude's a moron and thus a perfect target demographic, but I gotta refresh like every ten minutes, this is lame" and move onto someone else?
