Team Anna!
Going first - might as well! Ariel didn't have an issue with it, even though she wasn't exactly the toughest, but the mermaid was resourceful, feisty. She's resort to everything and anything to ensure that Anna's closing of the portal was successful, and the stupid thing can take all these stupid demons back with it - wherever it came from - too.
Gut instinct did admittedly scream 'pit of demons.' From the distance, the portal didn't exactly look like a small one and from the beginning, she observed that the bigger they were, the more monsters poured out, moaning and scouring the territory for a prey to rip apart.
"As quick as possible would be nice," quipped Ariel, and her eyes went to look at Isaac warily. "If you can smell them - how many do you think are there?"
