All I know is that Eva is definitely a requirement for the Cassandra restoration event, I'm not sure but I think if you miss her and progress too far in the game ( I think past the Grangold Mission) you cant recruit her anymore, which means you cant do the time loop event.That's what happened to me and I had to play through most of the game again just to recruit her so I could play through the time loop.
