Fortunately while the cyclone didn't really control, it wasn't self-sustaining, once the spell ran out the currents slowed and returned to normal. The ice pyramid wasn't conjured, just cold water in the sea. It'd melt eventually. But that would take a lot longer to vanish. At least until it came dislodged and floated to the surface.

Abby didn't wait for Dean to make his way back, she just got her knife working, tapping the tip of the blade to blobs of slime, freezing them, and sending them towards the surface. She'll take a little while to get most of this slime off the seabed.

It's not all of it. But it'll make this whole thing a lot less slimy. I'll need to go up for air soon. See if you can find a way to dispose of this gunk?

Her focus was pretty solid while she was working on a limited timeframe. So she'll just ride that out. She does spare a glance for Dean before adding another thought.

You're absolutely coming back and doing that for fun later aren't you?
