S2, E14: When Monica's parents clear out her old room to install a gym, they unearth an old video of her and Rachel's first prom night. It's obvious from this that Ross is in love with Rachel and, having told him it will never happen, Rachel changes her mind. Elsewhere, Joey gives Chandler a hideous bracelet as a token of his friendship and is mortally offended to hear Chandler saying how terrible it is.
