Maybe it’s already been said, but any age gap between Stiles & Derek is officially insignificant, if that’s anyone’s reason for being against them. Kira’s parents have 800+ years between them. And people who argue that the twins being with Danny & Lydia is okay: we don’t actually know the twins’ ages. We assume they’re younger than Derek, but that doesn’t mean they ARE. I think the age gap between Kira’s parents paves way for Sterek, because of their HUGE age gap. It says the gap doesn’t matter.
