Yes.so you can Stop the threesome with the Alien and put a stop to that scenario?
With a simple choice when prompted..
And the choice is even reflected until the end of prologue.
Violets thoughts at the end, even reflects that the MC ditch her. If you chose to.
(I was stuck with a 0 scene playthrough at end of ep1. and most of it is somewhat fairly consistent. Except for a part with a "sherry" as mentioned.)
