Maya looked pretty cheerful when she left the class. She smiled after Ashley and Sarah told that they missed her. Sarah also apologised for the mistreatment. She realised that the HOTs did care for her. Compare that to the beginning of the episode where she thought that they all were out to get her.
She still has a beef with Quinn, which won't be easily resolved, but now that she knew what the rest really thought about her, there's a chance that she could return.
The only possible obstacle is how they would react to her relationship with Josy. While the HOTs had no issues with friends fooling around, we don't know how they would view a genuine relationship. So far Sage was the only one who knew, and she was supportive.
