harles: *on ice

harles: *full of plants

harles: whatever you get it

harles: perfect siren material

harles: red i can hear your fond-but-exasperated sigh from the kitchen

red: It might be better to keep track of her than to leave her alone.

red: What say you, almighty admin?

kitty: harley, last time we let you invite anyone to anything, it was the housewarming party

kitty: and you ended up inviting everyone we've ever met, including WONDER WOMAN

harles: and she was really kind!

harles: gnight cat!!

harles: ahem ahem

harles: by the powers invested in me i hereby declare

Killer Frost has been added to Sirens <3

harles: cait is now a member of the midnight society!!

Killer Frost: ‘sup everyone.

red: And hello to you too, Frost. Nice to make your acquaintance.

red: I'm Ivy, by the way. Catwoman’s in here too.

Killer Frost: ladies’ book club? fine by me

harles: you get situated in gothm ok cait?

Killer Frost: well enough? there's a LOT of underground cold-proofed rooms in this city

red: Mr. Freeze has probably forgotten about more cold rooms in Gotham than have been built in any normal city.

harles: thats the fun thing about gotham you cant swing a stick wout hitting an abandoned safehouse

Killer Frost: already learned that the hard way. I tried an old steel factory first cause of the heat and it turned out to be a den of joker goons

harles: J is using the sionis steelworks again? hagshsgsfsc

harles: time to open my private line to bats i fucking guess

red: What do you mean “for the heat”, Frost? I would've assumed that would be a turn-off for you.

Killer Frost: you'd think so, yeah

Killer Frost: i dont work the same as Freeze, my powers work by stealing heat from my environment.

Killer Frost: i kinda need it to maintain a normal body temp

Killer Frost: i can survive without a heat source but it feels like

Killer Frost: um uh

Killer Frost: being awake for a week straight with the world's worst hangover

Killer Frost: so yeah consistent heat source = good

Killer Frost: sorry for rambling

harles: its all good caity! we would’ve had to talk about it anyway if you two ever meet irl

harles: ill give you ivy's meetup safety sheet later

red: I still hate that you made that

red: I acknowledge its necessity but i hate its existence.

Killer Frost: i wanna circle back around to harley having a private line to the bats??

red: Batman gives his more “gray” villains special crisis lines.

red: Cat and Harles have had theirs for a while, I got one more recently. 

red: Though tbh he's probably hacked every device the three of us own anyway, so screw us I guess

Killer Frost:

Killer Frost: please don't tell me i just talked about my one weakness in a chat that Batman might be reading

harles: ah relax hes not in here red's just paranoid

harles: we have an understanding, him and i

red: And we have a firewall.

harles: and secret codenames!! cait we gotta pick a username for you!!!

Killer Frost: oh um

Killer Frost: i haven't had to come up with one since i was normal and had a WoW account

harles: nerd

red: nerd

red: Take your time, anyway. Only the admin has permission to change names in this server and Selina's going to be asleep for a while.

Killer Frost: first, wow rude :(

Killer Frost: second, harley is admin

harles: ?

red: …No, Selina's the server admin.

Killer Frost: scroll back up, i was reading through all the previous messages

Killer Frost: (i'll be careful around your plants btw)

Killer Frost: catwoman didnt just make harley moderator, she made her admin

harles: !!!

harles: holy shit ur right

red: She must've been so drowsy she clicked the wrong setting.

red: Harley.

harles: :3

red: Harleen Quinzel.

Killer Frost: wait is that your real name??

9LivesCapulet: what in the hell happened here

Notes:

I'm a huge fan of chatfics, in particular Guessing Games by phoelynfabulous, so I wanted to write one of my own! I borrow a lot of stylistic cues from that one, but the plot and interactions are all me.

Feedback is welcome. If I keep writing this it's going to include a ton of different supervillains, and juggling that many characters is always a hassle. Any typos are on purpose if they're in Harley's dialogue, and unintentional otherwise.

2/13/24 - made slight updates to Killer Frost's dialogue now that I've researched her more. She's really growing on me, I'm excited to write her more! She's canonically allergic to cinnamon.
