Unravelling is the third subchapter of Chapter 5: Mirror Temple in Celeste. The subchapter formally introduces Seekers, red walls, and barriers, as well as corrupted spikes. At the start of the subchapter, Madeline will confront Badeline multiple times asking her what's going on, only to realize this wasn't her doing at all.
Gameplay[]
This subchapter is very linear, having no branching paths. In the fifth room of the subchapter, a Seeker will break out of a background statue as you pass it, and these enemies will continue to appear in the succeeding rooms. Many rooms will involve collecting key tokens scattered all around a room and potentially utilizing Seekers to grab them as they will collect them for the player if touching one while charging. None of the rooms here will have more than 1 Seeker.
Strawberries[]
There is 1 Strawberry found in this subchapter.
Berry 1
Found in the sixth room of the subchapter, you'll need to lure the Seeker into the red wall on the right to break it and expose this Strawberry as well as a spring.
