A cliffhanger that turns out to be something completely banal? Percy Weasley makes life annoying for everyone, including the reader!
Did Granger and Tonks just leave Harry restrained in a cell? Yes, but the Department of Magical Law Enforcement (DMLE) operates on a strict schedule, and there will be other people along shortly to take care of Harry's physical needs.
Also, with this page, Voldemort's Children finally passes the Bechdel test. (The Bechdel Test is “(1) it has two female characters in it who (2) talk to each other about (3) something other than a male character”. For these purposes, I'm just assuming that all the characters are the gender the other characters refer to them as. Granger and Tonks talked to each other on the first two pages, but it was about Harry.) It took this long because almost all conversations so far have included Harry. By comparison, if Harry was female, we wouldn't have passed the reverse test yet (unless you count James and Sirius when they were bullying Snape), and wouldn't pass it until chapter seven, when there will be a flashback where Dumbledore talks to the young Tom Riddle.
