… I’m never gonna live this eyeliner thing down, am I? XD Well no putting an end to it now! Might as well feed the flame.
I imagine that when giving tips, she ends up giving tips for other kinds of make up in case Sonic might be interested in trying other things but he’s only really interested in eyeliner. However, he doesn’t stop her because he knows she’s just trying to help and he appreciates it. <3
I was also thinking about the first time he wanted to try eyeliner and he turns to Amy for help because who the heck else is he gonna ask?
ALTERNATIVELY, consider this: Maybe Sonic is self taught and he’s the one who gave AMY tips on eyeliner/helped her figure it out. ;0
