Watch as Jason Priestly uses his Brandon Walsh charm to hook up with Heather who, oddly enough, was dressed as a mermaid. Sure, he wasn't playing Brandon but that's how we know him and that's who he'll referred to as!

Supposedly this isn't a one shot deal and his character will return for a multi-episode arc. Now, if only we could get Jennie Garth and Tiffani Thiessen in the mix somehow.
