I said this in the official Becky thread but it belongs here as well.
There are visual warning signs to type 2, you see them all in Amber. If it's untreated, it can spiral out of control very quickly. Most cases, people who experience type 2 diabetes are fatigued. It isn't too far fetched to believe zombie Becky was due to her diabetes.
Becky is smaller than Amber, there is absolutely no way in hell that Amber isn't a diabetic. If she doesn't face reality, she could also be a type 1. If she is type 1, it's game over from here on out.
I REFUSE to believe that Amber is not a diabetic, this is getting to the point where lying about it just makes her look like a fool.
