A spoiler warning for the more recent chapters in the manga Magi(takes place after the time skip)
BEGIN SPOILERS
So you know how Alibaba reunites with everyone when he returns? I've been rereading Magi and I noticed that when he meets Jafar again he notes that the guy hadn't aged at all. Jafar's expression remains the same for two panels and then he bursts into a smile. Alibaba then wonders to himself if he said something weird.
I'm pretty sure with the way everything was presented this isn't something to brush off, I just haven't heard much about it since. Did the manga ever mention anything about Ja'far looking younger than usual?
Also, who's read the raws for chapter 330? Things have gotten pretty rocky and interesting!
