Since Sunshine seems to have such a likeable personality, I wonder if they encountered each other on the island and she greeted him. Perhaps he mistook her friendliness in a way that made him get excited and also realize he could overpower her without anyone seeing.
idk. Just tossing ideas around.

Yup, they were both reportedly regulars at the capground and it's entirely possible that they were familiar with one another prior to the attack.
