Evelyn and Alice

[Enherijar]

Does opening Evelyn's door lock you out of Alice's content?
Does ignoring the door and meeting Alice lock you out of Evelyn's content?
Is it possible to have both characters meet since it's kinda clear that Alice is supposed to be looking for Evelyn and Evelyn hiding from Alice?
