Baby it's cold outside

Laas: (Shapeshifts into literal fire and/or takes the form of a space-dwelling creature that's fine with the cold, vacuum of space)

Odo: Quark, I'm cold. It's my turn with the coat.

Edit: Nevermind. Snarked before I thought. That was a few episodes before The Begotten and Odo was humanoid at the time. That'll learn me to not do the internet before my morning raktajino.

Does Odo become brittle in cold temperatures?

You try and keep a changeling inside! I'm not making my house airtight and I definitely can't afford a Cardassian force shield to do it.

But only if they pay!!

Help! I brought them in, and one of them turned into a puddle!
