Never.
They fell on each other and kissed, so yes I think they fell in love after that.
Rouge the Bat.
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!
Yes, in a sense, Shadow does care for Rouge. He may not love her, but he certainly does care for her.
Of Course! In my opinion, they do! Rouge The Bat and Shadow The Hedgehog... They make a well couple, Rouge is a white bat, and Shadow is a black hedgehog. Now whoever is reading this, DO NOT TAKE THIS RACIST! THIS IS NOT RACISM! Thank you for understanding!!
she flirts with both shadow and knuckkles
No. But she does like Knuckles and Shadow.
Rouge The Bat. She wish she can been shadow and trying her best to get shadow to love and taking her a long time and hard to get shadow to like you for a start and love is much harder so its rouge the bat who loves shadow
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.
No, Shadow doesn't have a romantic relationship with anyone.
In episode 145 prize fight he gets kissed by rouge
Especially yes their perfect
