Frollo had just fallen to his death, and Esmeralda was holding on to Quasimodo. But she couldn't hold on any longer and she let go. Quasimodo fell far down but Phoebus caught him.

"I saw the way you looked at her, Quasi," said Phoebus.

"I'm sorry, I love her," said Quasimodo.

"Well, I can't risk something like that to happen, Quasimodo. I know we've been through a lot, but I can't help the fact that Esmeralda will fall for you. I'll regret this for the rest of my life, but, Goodbye Quasimodo."

With that said, Phoebus let go of Quasimodo so he could fall into the fire and die. When Esmeralda asked what happened, he told her that he was trying to lift him, but couldn't. Despite Esmeralda being so sad that Quasimodo was dead, she married Phoebus anyway. Not knowing that HE was the one to kill Quasimodo.
