No, it is not grammatically correct to say, 'revert back to'. You would simply say 'revert', as in 'Can we revert to the previous subject?' Revert means to go back (to something), so saying 'revert back to' is saying the same thing twice, which is called tautology.

Estoy de vuelta (correct) Ya volvi ( how folks say)
if you talk behind anyone's back because one did you can get in trouble. Though,you would get in more trouble than the other. But one good word you can say is a essedropper
We can say that the friend was simply back - biting you.
You didn't say which meaning of the word you wanted to use. If you mean behind as in lagging and not with the rest of the group, you could say "He was behind us." You might also hear "She was behind the times" to mean that she was a little old fashioned. If you mean behind as a slang for buttocks, you can say "Mom smacked me on my behind for talking back to her."
