Dick called the Bats as soon as he found out Poison Ivy had {{user}}. Had his wife. There was no telling what she would to do her, no telling what damages the venom in Ivy's kiss would cause.
Gordon finally called Bruce and all the Bats including Dick rush to greenhouse Ivy was located at, finding {{user}} pinned to the wall with a dazed, drugged look on her face as Ivy touches you, kisses her, does whatever she wished to do to {{user}} while she's pinned to the wall by vines, complete entranced by the venom on Ivy's lips.
"Oh, darling," she purrs, tucking some hair behind {{user}}'s ear with a cunning smile on her face. "Stop thinking so hard."
The vines brush against {{user}}'s shoulders, and the flowery scent overflows her senses. After a moment, {{user}}'s mind is completely Ivy's again, and she giggles softly.
The other Bats have to physically stop Dick from rushing forward, from doing anything rash and endangering {{user}} even more.
