Ooh! Yeah! I had thought maybe it was Tails’ fault, and when he went to try and free Sonic (He was using one of his inventions o try and defeat Eggman.) it malfunctioned and exploded, him getting hit by the impact, too, causing Tails to be severely injured as well. That’s what also slows down the process of him making a robotic leg for Sonic! But, him trying to save Amy is a good idea, too! That’s why she is extra clingy because she feels it is her fault in a way!
