So it seems like Eren either went off the deep end or finalised his master plan about 10 months ago...But the wiki article says he's under lock and key and only gets to meet with Yelena while Floch is guarding him..I'm probably missing something completely obvious, but why was he locked up at this point? I mean this is before he goes AWOL and then does a reverse-Bertolt on Marley. Was he locked up for opposing Zeke's plan or what? Feel like I'm missing something obvious. Cos either that or he goes from building rails with his friends one moment to being locked up the next?
