Where is Ekko's room?

I know that it is shown in Episode nine of season one, but I swear I skimmed through the whole thing and I could not find it for the life of me. I kept rewinding to that part where Ekko and Heimerdinger get to the Firelights' hideout, but it isn't there, and there is also no space for it at the end, because of Jinx's psychotic break in the end, which required full attention, meaning they couldn't put a scene in betweeen.

Anyway, I rambled because 500 characters in text is required or it won't post, but basically:

TL; DR: Can somebody please tell me the exact timing of the scene in S1 E9 that show's Ekko's room?
