Brie, who plays Annie, explained that the connection between the pair is "still too subtle for the other characters to notice".
"It's very vague and we're not sure if it's just an attraction or something more," she told TV Line.
Brie hinted that Annie and Jeff (Joel McHale) will begin to notice the growing feelings between Troy (Donald Glover) and Britta (Gillian Jacobs) in the third episode.
"[We] get a little territorial, like, 'Wait a minute - we want each other [but] we don't want you guys to be with anyone'," she teased. "It's very incestuous."
Brie and McHale recently revealed that the Annie and Jeff romance will be "pumped up" when the show returns for its new season.
Community will be back with new episodes on September 22 on NBC.
