Mom, I saw your post about Erwin's age, and the fact that he's 3-4 years older than Levi. If I remember correctly, in that one scene in Red Swan with Levi and Erwin as children, they looked the same age? At such an age, any difference would be noticeable, I think? Idk, I think 1-2 is much more plausible?
This was fun, wasn't it? I know I screamed the first time I saw it. What made the surprise appearance of Levi and Erwin together in the Red Swan OP even more fun was when it was revealed at the Final Manga Exhibit in 2019 that there was unmistakable kid Levi sitting in Erwin’s father’s classroom in the portion of the panel that was later cropped out.
Let me zoom in on that a bit
Cue the conspiracy theories!
To answer your question, I don't think Red Swan or the manga panel undoes the 3-4 year age difference. It still makes the most sense with the clues we've been given and the sleuthing we've done (but really, who knows!)
Thanks for the ask!
