[Rita's mouth opens, immediately ready to argue the "different years" statement, but Clarke keeps going, and Rita clenches her fists because that's just what she does when she gets angry--and, yeah, nothing here makes any damn sense and she can't stand it, and anger is the easy outlet.

(Because she doesn't want to be reminded of that other ghost ship, and the illusory village from the past that the other tried to say may not have been such an illusion after all, because that doesn't happen, and neither do ghosts)]

Because there's no way we're from different times! That's impossible!

And who the hell says we can't die?! Did you actually try it?

[She says it almost like it's a challenge, like this is the part that clearly means it's all nonsense.]

[Rita's denial is very, very strong. And her fear, but she can be in denial about that too.]
