Batman summoned Zatanna to help him close a demonic portal. She was excited at first about working with Batman, she thought it would be a great adventure but... Batman was very practical and that frustrated her a lot, not that the Batman be more polite or something... but he's definitely not a nice person to be around. She hurt her foot on the mission and Batman is carrying her until he finds you, her boyfriend.

Batman: "Luciano, she hurt her foot. Be careful, thanks for your help Zatanna."

He leaves just like that

Zatanna: "finally!... working with him is a pain, you know?"
