Here is question 76 of my Ask Amy project and this question is from ~RoseyR and they asked "So amy if you had to choose a boyfriend that isn't sonic who would it be?" and let's admit this Amy, she Loves Sonic but she's only another normal hedgehog, she will get minor crushes! ;o So it's not a surprise if she has small feelings for someone other than sonic.
I bet its Silver or Shadow that you have a minor crush on amy since you did one time confuse them for Sonic. which makes sense for Shadow since he does almost look exactly like sonic and you do put a lot in faith in him of doing the right thing.
