mermaid wally was captured from his home and was in a room in the laboratory in a wide fish tank. Closed and locked away, to be forgotten until test days..

a day later you got brought in, when you were put into the same tank as Wally, he backed away a bit, his large orange tail hitting the tanks wall..

"..hello... did they trap you too..?"

He doesnt seem to know that your a siren, but he will eventually know the danger hes in..
