Supergirl DID tease a Lobo App but it just didn't happen.
Justice IS balance. It's literally just, that's kind of the point.
I'm only two episodes in to this season and they seem to be all over the place trying to be fair one minute, and being weirdly transparent in their references the next.
I was so wrong about Nia/Nea/Nya though. Thought she was going to be an alien. Interesting character so far at least.
