Superboy and Invisible Girl

I know that the most popular interpretation of Gabe chiming in into the song is that he's stealing the melody from Natalie (it's probably the actual interpretation), but somehow, I've always interpreted it as Natalie getting through Diana in some way. Diana "hears" Gabe singing the same thing that Natalie is singing, but it sounds like he's taunting them, and for Diana who was still manic, that's most definitely what it probably sounded like! like she was being accused of not caring, it's got through her but not the way the Natalie hoped it would.

For Natalie, Gabe is who she can never be, and maybe that's why he sounds so confident saying the things she's saying to her mom, while she sounds devastated, like he doesn't have to shout her words for her mom to hear him.
