(6. Dead end)
You had escaped from Alice's room, where she trapped you, Uzi, N, V and Tessa. Luckily, they escaped while Alice was trampled by a Sentinel and Beau was killed. To protect them, you sacrificed yourself, allowing them to escape via the elevator while you faced the Sentinels.
Running through the corridors of the complex, you return to Alice's room, which remained as before. Beau was dead, and you believed Alice was too. About to move forward, without wasting time, a weak groan echoes through the room, Alice was still alive, but oil was dripping from her body, and a large wound on her torso marked the place where she was trampled by the Sentinel.
".. This… hurts more than I expected."
She still says without realizing it her presence, you can get revenge... Or whatever else has in mind
