>>113434400When I watched Locked Out originally, I didn't think that was even what was being indicated. I thought Reggie was just afraid to engage in a more mature, grown-up version of the game she was already playing with the action figures at school. Usually grown-up things are either gross or boring to Reggie, like puberty or buying dresses, so they're easy for her to reject, but here was something that she would actually have had fun with.
The reason she blushed when Connolly caught her playing with her dolls, I thought, was that for the first time in her life she was ashamed to be behaving childishly, on some level she really did want to join them instead of retreating to child's play, her no longer being able to go to Forever represented the uncertainty and confusion she felt because of her desire to do something mature for once, and the reason she was able to go to Forever again after formally rejecting Connolly's offer to design sets for them was that she'd reaffirmed her commitment not to grow up in any way.
She got the resolve to talk to Connolly after her teacher gave her the pep-talk about how her "sense of play is the most powerful thing" about her. He was only trying to cheer her up, but she took it as an endorsement of child's play over the more adult activity. Without meaning to he encouraged her to retreat from the one grown-up thing she actually would have liked, and that's literally what she did, all the way back to Forever. Like so many other things in the show it's a victory in Reggie's eyes while in reality she's becoming more withdrawn.
Rewatching the show I do see where the lesbian interpretation is coming from, and it probably is what was intended by the writers (I haven't heard any word-of-god stuff since I only got around to watching the show this past week), but I kind of like my original interpretation better.
