When you turn to your partner and you're both are thinking, "Shadow is right."
Sonic Prime is very frustrating!!! Also if I were writing it and had Sonic being like, "Nines is a good guy!" I'd have Shadow go, "Like I'm a good guy, right?" and then have Sonic have to think what it means to be an anti hero because COME ON he's going to betray Sonic, right? RIGHT?!
