it must have taken time to find the jobs that Kai, Jay and Cole got in season 4, but when we cut to Zane in the first 'real' scene, (where he has a conversation w/PIXAL) it appears that not much time has passed. though I suppose he might have been comatose during that time, seems like an awfully long time to stay unconscious.-TheAmberShadow
I think it was actually a year between season three & four. The reason why Zane didn't act like it was a long time, was because of Clouse's taser. I researched the effects of a power surge on a computer, & some problems are damage to storage (memory) & RAM. RAM is sort of like short memory for a computer, it's where data goes before it's permanently stored. What I think happened, is when Zane was first captured, he tried to escape, & Clouse tased him. This would have been like a power surge to a computer. It corrupted his already saved memory & threw his RAM out of sorts. This would have made it hard to store new data (memories). That means he could have been on Chen's island for a year & he wouldn't remember due to not being able to retain new memories the computer's equivalent of short term memory loss. Like Dory on Finding Nemo. With his longterm memory corrupted as well that would be why he couldn't remember Pixal for a while. As advanced as Zane is, he's still a computer. Any more plot holes?
