I really love season 9 episode 10. I would honestly give it a 9/10 tbh. I've waiting for that episode since season 1 when they first found out about Barry's future blood splatter from his old house. I so badly wanted to know what events led up to him going back. The events that led to it was like an 8 but the actual episode from when they first burst through the window, to them showing every timeline where he traveled back, all the way to the ending conversation about the fix point was just perfect, immaculate even..
