It is obvious Ross likes laura by the way he stares at her in videos.In this one video of R5 Ross compares his life to Austin's and says their I'd no relationship between the two of them except friendship but he's blushing. His brother says to him in a intending way so your single basically saying he can tell you have feelings for her.Also Ross says in an interview that he likes a girl who is outgoing and does whatever she wants not caring what others think and Laura is like that.
He doesn't like her, she doesn't like him! They are just co-stars! Ross and Laura will probably never become RAURA! And if they do great. But don't big them about it! Will you get mad and not like them anymore if they didn't date?
