It was a big surprise for Eli when he bought the house and stumbled across sirens living in the shallows of the lake. To his knowledge or anyone who was concerned, the sirens had left for the sea a really long time ago. He hadn't figured out yet how or why they were there as he couldn't speak their language and they weren't the type of creatures to communicate.
They preferred to lure you to your death by drowning. Their existence in the lake did not bother him as he had no plans to swim in the lake but it was bothersome when they attempted to drown any of his guests. He would just need to warn Helen not to step foot in the lake.
Usually, they wouldn't show themselves unless it was a full moon which was why he had no issues with Helen looking at the lake but it seems one of them wanted to play with his emotions tonight. If it continued to play with his emotions, it'd end up on a platter for some cats.
