Alicia's health is declining.

Everyone is leaving the radiation zone in rafts to escape an onslaught of walkers.

Alicia wants to go back to the tower in case people heard her message and are in danger.

She keeps seeing a younger version of herself.

She saves Strand's life and they both make it back to the beach.

Alicia plans on going in a raft alone, and when Strand offers to go with her, she says no.

She doesn't want to put anyone in danger by turning while they're on a raft.

Strand is upset, but she decides to stay alone on the beach.

Morgan radios her and tells her he's out of the radiation zone, so there is a way forward, but is it too late for Alicia?

She has visions of her past and tries to confront her sadness over what transpired.

In the end, she wakes up, some time later. She's made a miraculous recovery and looks healthy.

She prepares to search for answers she needs and survivors.

The handling of the scene makes it seem like Alicia is dead and this is a version of the afterlife on the series.

We'll never know... unless Alycia Debnam-Carey returns.
