Trying Human/WMG

The baby in the opening is Phillis and EBE1's kid.
Possibilities include...
 * Hue. He has human emotions, blue eyes like Phillis, and before the author took the characters' ages off the fact page, it listed his age at around 50. The prologue took place in 1947. Not to mention, Phillis asked about him in Rose's hallucination (Or Was It a Dream).
 * MJ-6. He's half grey and half human. It's the logical assumption.
 * Rose. She clearly has a connection to Phillis, and Jar-Phillis knows who she is. EBE1 says something red is coming, and there is a possibly that this refers to Rose's hair. As for her age, the ability to keep someone's age suspended apparently exists.

Alternatively...

The baby in the opening is a Child By Rape between Glasner and Phillis.
The baby being EBE1 and Phillis's seems suspiciously obvious, so it could in fact be a Red Herring. The comic's made it pretty much clear what Glasner's intentions are, it's been built up, and science would be more in favor of that than a naturally occurring Half Human Hybrid. Possibilities include...
 * Rose. See above.
 * Pretty much any human whose parentage isn't clear, especially those who look like they could've been born around 1947.

Emy Bitner is an alien.
She's still a little naive about how Earth relationships develop, but she's getting there.

Rose and Phillis are multiple personalities.

 * They're the same person due to time freezing, like Dr. Glasner.

Katy Perry got the idea for "E.T." from this comic

 * Not my theory (someone on Fandom!Secrets came up with it), but it does work when you look at the lyrics, Unfortunate Implications and all.

EBE1's real name is...
I have several guesses.
 * Tint
 * Tinge
 * Color
 * Saturation
