Never.
Never.
No, Rouge has never kissed Shadow.
Rouge has never kissed Shadow. She does kiss Tails on the cheek in one episode though.
They fell on each other and kissed, so yes I think they fell in love after that.
No
Not that I've seen, Shadow usually keeps more to himself, often blanking the world out in the process. So, I'd think not. Maybe off the scenes, yes, but not on film. Besides, Rouge usually flirts with Knuckles, Sonic, and Tails, to make THEM blush. Ecspiecally Knuckles. Don't forget that she kissed Tails in Sonic X.
There are no canon couples within the Sonic series so far, whilst this may change in the future, it is highly unlikely that Rouge will tell Shadow that she loves him.
Yes in fact I think she kissed him! they do kiss but only in the Japanese version.
There are a few hints of this in some games. But not and specific signs of effection. Plus, Rouge love interest is Knuckles. Moreover Shadow is indifferent to Rouge.
Rouge has friendly/business relations with Shadow and nothing more. Shadow does not test any feelings to Rouge and she knows it. Although she does have a slight attraction to him, but shadow doesn't return the favour
No, Sonic the Hedgehog likes his friends that care about him, though Knuckles has a small crush on Rouge the Bat. Yes! It has been confirmed that Shadow does like Rouge! Think about it Shadow is always there for Rouge when shes in trouble. If he hated her he would not do anything!
It isn't Shadow and Rouge. I know it looks like they're together, but Shadow is a loner so he isn't with anyone.
