So Obama was president on Earth-1, but we know that President Cannon Fodder and VP Susan Brayden were in office in December 2016. I
The Legends basically ripped off this canon violation from last month's Scandal/How to Get Away with Murder, where Barack Obama has been the constantly mentioned president in HTGAWM, yet Michaela, and the world's biggest fan of the Obamas, is dying with excitement to meet former President Grant during the third term of the Grants. Are you allowed to plagiarise canon violations? ABC should sue.
It's very possible Barack Obama was up to something very different, perhaps not even politics. I think Mick likes him, and I don't think he'd have liked
anyone in power. Or maybe Obama was just a president at a different time. Not that we can take the identity of the president as a constant – Beebo day didn't stick, but John Diggle Jr. and Captain Jiwe rum stuck. Whoever was president, maybe he is not any more.
A bigger problem would arise if they ever tried to integrate Black Lightning into the Arrowverse, where Obama is the president and Supergirl is a role model (it would be worse if she's a fictional one).
I thought that was pretty clear myself.
Pretty clear, but also not very smart on Damien's part. If Nora was so gone, and it was only Mollusc left, how they fooled her/him by playing his own voice in her/his ear? If you watched and thought Damien couldn't be fooled so blatantly, the episode doesn't add up to you.
