The Wizard decided to fulfill Nate's request, and he wasn't going to rush to the rescue.
Sirte couldn't stand letting Nate and the others die, even if it meant sacrificing himself, he wanted to live and die alongside Nate and the others, making Angel a historical term.
These are two different decisions made by two people. Comparatively, the Wizard's decision is much harder.
Sirte's words left the few people of Angel conflicted, and after glancing at the Wizard, Sirte whispered, "Sorry, take care."
Sirte turned and left the house, and after exchanging looks, the Prince said to the Wizard, "Sorry, I really can't do this. This is the first time in my life I'm disobeying an order, Wizard, forgive me."
The Prince bowed his head and walked out of the house.
