Pause at 10m30s when One says 'join me'. Skip to 1h32m30s-E/8m10s-R. This scene is pretty vital to the story so it might be worth watching if you can tolerate the violence/imagery, maybe just close your eyes as needed. This scene is followed immediately by the next censored section which is the concluding scene. Again, still violent but recommend watching if you can.
Eleven responds 'No' and throws One across the room. One gets up and they briefly appear in a stalemate as they use their powers against each other. Eleven appears to weaken as she slides backward but then gains her footing. She recalls One's earlier advice to use a sad/angry memory to channel her powers. She has flashbacks to being attacked by Two and the other bullies, as well as the scene of the children killed by One. It is not enough and One throws her against the wall and then drags her back and levitates her in the air in front of him. Eleven is in bad shape and looks like she is about to be killed in the same manner as the victims of Vecna. The scene darkens to black
Spoiler

The scene starts glowing red and we hear a baby crying. Eleven is having a memory of just after her birth and her mother calling her Jane and telling her she loves her. We come back to Eleven in the rainbow room gaining strength and throwing One through the mirror and against the wall in the adjoinging room. It cuts to Eleven in the real world in the NINA pod, lights flicker and monitors get erratic. Dr. Brenner says 'It's happening.' Back in the rainbow room Eleven outstretches her arm towards One and screams. He begins to glow and disintegrate into particles and the wall glows red. We see that Eleven has created a gate to the Upside-Down. One falls through clouds and is repeatedly hit by lighting. He is being burned and disfigured. The scene cuts to Vecna and a tentacle moves to reveal the 001 tattoo on his arm. The episode ends.
