What happened to Henry at the end of Chapter 4 in Bendy and the ink machine?

in this Chapter Four DLC, follow the fading trail of a stolen friend and survive the cartoon horrors that await you. The secrets of the studio are stepping into the light and it's time to face them.

Henry wakes up in the remains of the crashed elevator and begins his search for Boris. He journeys through the studio's archives, suddenly beginning to suffer from hallucinations of paranormal activity and discovers a large group of non-hostile ink monsters called the Lost Ones, hinted to be the studio's employees. They have been driven to despair at being trapped inside the studio for so long, crying that they just want to go home. Henry then also encounters "Bendy" again, who surprises him, but then strangely leaves him alone before disappearing.

After navigating through the vents of the archives, Henry finds himself in a large underground warehouse that houses prototypes for a Bendy theme park, Bendy Land. Created by park designer Bertrum Piedmont, more audio logs imply that Joey intended to take the credit for the park's creation, leading Bertrum to become frustrated with the studio owner. Henry is taunted by the disembodied voice of "Alice", threatening him with the idea of the captured Boris being used to finally cure her disfigurement before he can reach her. Having to travel through different storage areas of character suits, Bendy animatronics, ride prototypes and even a railway system, Henry learns from a recording that Joey's focus on belief and dreaming was nothing but a facade when he drops the attitude and remarks how the public love messages like that, complaining he can only do so many takes of such rhetoric a day. During his time in the prototype ride storage, Henry is attacked by the corrupted form of Bertrum, who has somehow been transformed into one of the park's attractions, forcing Henry to destroy him. In the railway storage, Henry is also stalked by the Projectionist again. After being spotted and hiding in a "Little Miracle Station" from it, Henry witnesses "Bendy" arrive and the two monsters fight each other, leading to "Bendy's" victory after he pulls off the Projectionist's head. "Bendy", once again, confusingly leaves Henry alone and departs with the Projectionist's body.

After activating the haunted house ride to reach where "Alice" is hiding, Henry is stopped by Boris, who has been turned into a hulking monster by "Alice" in order to kill him. With no choice but to defend himself, Henry eventually manages to kill "Brute Boris". Enraged at having been foiled again, "Alice" charges at Henry in an attempt to kill him herself but is suddenly stabbed through the heart from behind and collapses to the ground. Henry then realizes that he has been saved by another Alice Angel named Allison Angel (who is heavily implied to be Allison Pendle) and another Boris named Tom (possibly the studio's repairman, Thomas Connor), both armed with weapons.

In a post-credit scene, "Alice's" body is shown lifeless on the ground, surrounded by the Lost Ones. However, through the humming that is heard faintly in the background, it suggests she might still be alive.
