Similar to what I've said about The Riddler, Poison Ivy has probably such an up and down relationship with the Robins because they are all such different personalities and she's just never really sure if they're fucking with her.
Dick: *strung upside down with vines*
Batman: *strung upside down with vines*
Dick: Holy Hydrangeas Batman!
Ivy, grinding her teeth: For the last goddamn time. It. Is. Mint.
Dick: Holy Minty Fresh Feeling Bat-
Batman: For the last time, shut the fuck up, Robin. She's going to bust my other rib.
Ivy: It's too late Robin, Batman is under the control of my lilacs. He cannot hear you, so twitter away, little bird.
Jason: Oh that's what lilacs looks like.
Jason: It's Jane Austen's favourite flower. I thought they were just purple, you know, lilac. But these are blue and pink?
Ivy: Uh, yeah. Lilacs can be white too.
Jason: So cool. Do you know they belong to the olive family? And they symbolise first love?
Ivy: You know what, you can have Batman back for that. I'm actually impressed.
Tim: Hi, Miss Ivy, look I get that you're doing a whole thing here, drowning Wayne Enterprises in moss and yeah, total respect but could you maybe do this tomorrow?
Ivy: I'm reclaiming the earth one high rise at a time here Robin. Mother Earth is dying.
Tim: Again, total respect but I got this science test tomorrow and I still have zero idea about the difference between thylakoids and chloroplasts in relation to photosynthesis-
Ivy, sighing: Have you a notebook?
Ivy: Mother Earth doesn't have all night, Robin. Do you have a notebook?
Tim: I have a paper one if that's-
Ivy: Just... It will have to do. Now, chloroplasts-
Ivy: um, thanks. But like I was saying, if the city won't stop the production of aerosols, I'm going to let the vines drop Bruce Wayne from this high rise.
Steph: No, I get that. It's just, I'm so glad somebody else gets it. Like men do not have to wear deodorant that strong or in that high of a quantity. Really you're doing us all a favour.
Ivy: So, OK, you get it. So Bruce-
Steph: He's the worst culprit! I mean, I'm guessing because I've never met this random citizen.
Damian: You have gone too far, witch
Ivy: If my only have to kill every CEO to prevent the poisoning the habitats of Bog Turtles and save them from extinction-
Damian: Batman, she has a noble cause.
Batman: Buddy, didn't we talk about how murder wasn't the answer?
Damian: But the turtles have no champion, Father. They are as innocent as the civilians we save on a nightly basis. Don't we dish out violence and threat to protect them?
Batman, talking into comms while lugging Damian back to the Manor under his arm: Oracle, make a note to not allow Robin to have any contact with Poison Ivy while on patrol.
