I'm not sure why they bothered to turn Lily into a frenemy. She is only in two episodes and it's not like she was the most interesting character. They force a redemption plot for a very minor character because apparently the writers had no idea what else to do.
This would also explain why Cas makes deal, like John, Dean, Sam, Mary etc. Etc. Etc. This trope is really stale at this point.
