Everyone is looking forward to meeting the man who killed everyone. She must have told it the right way.

I'm pretty sure her 'dad' knew that saving Charlie would result in the timeline where he himself exists never occurring, as Charlie's death was the catalyst for his own creation. On the other hand, the timeline where he does exist contains nothing of value (to him) except his daughter. Being an actually good father, he would naturally wish to send his daughter to a timeline with opportunities and possibilities for life and interaction she could not have in the ruined future where they both exist. Her father would have known all along that sending his daughter to save Charlie would negate his own existence, but giving his daughter a chance to live a proper life with real people in a non-destroyed world (using the 'person who causes a time-diversion survives it even if they should not' loophole) would be worth it to a good and caring parent, even if they are a genocidal AI.
I don't think her father ever intended to join her in this timeline, knowing as he did that her success here would ensure he never existed in the first place.

@Brent O'Gara: I like your explanation/hypothesis.
And I love this page. Their expressions, all of them, are great. Nicely done.

It's like a cheer from the Apple-less Indians at a Tom Slick race.

He created his daughter specifically to save Charlie and thus prevent the genocide. He did this because he regretted the genocide, rather than specifically because he wanted a daughter (page 412). But then obviously sending her to Sam's timeline gives her more happiness than staying in a timeline where everybody else has been killed.
And ultimately it seems it is all being planned, or at least nudged along, by Hyperion in the far future (page 387).
So far we have these timelines:
* Sam's timeline where Charlie never died and grew up to be software engineer Sam.
* Memnon's timeline where Charlie dies (page 383) and EOS creates Memnon (page 392) and the genocide happens because the military destroy EOS's memory (page 407).
* The timeline (which may be the same as Memnon's timeline) where a military agent from 2059 pulls Charlie into Sam's timeline (pages 8, 9 10).
* The timeline from which Rothwell comes from.

Note also that in page 412 Memnon seems to imply that EOS is EMI's mother.

Eos' and Emi's names are not acronyms. I don't know the origin of Emi's name (Emilia?) but Eos is the transliteration of the Greek word for "Dawn".

Also, show of hands, who thinks Charlie ends up with Emi, vs ending up with Ash? I'm not going to vote because I think he would do good and well with either one but for entirely different reasons.
