But working alongside the original gang isn't all that stands out to Sofia about season four, especially considering her character's relationship with Ricky (Joshua) takes center stage—though the couple are keeping their romance under wraps, for now.

"I think that adds such a cool level to their dynamic," Sofia explained, "because while they probably want to be holding each other's hands in public and hugging and doing what couples do, they can't because they want to keep it special just between them. But whether or not they keep it a secret for long, I think that it'll be up to the viewers to find out."

As she put it, "There's a lot of drama that I think occurs due to the fact that their relationship is a secret and that's always interesting to see."

The final eight episodes of the series will premiere on Disney+ Aug. 9.
