GhostBrotha!
Book #2 in the Sweet Valley High series mentions Todd Wilkin’s little brother. And then the series never mentions him, ever again. This greatly amused the Snark Ladies and every now and then, they find an occasion to remember GhostBrotha! or blame some random happenings on him.
Here’s the full excerpt from the original recap:
Sara: This is also the book where we get to hear about Todd’s little brother for the first and only time on account of him completely disappearing from the rest of the series. Maybe he wised up and got the hell out of Sweet Valley before the evil twins, the car crashes, the deaths…
Lorraine: YES. This is amazing. The Sweet Valley-verse may forget about Todd’s brother, but we? We NEVER shall. Every time something unexplained happens, I’m totes blaming GhostBrotha. I’m so excited.
