Harry Potter and Wiz Khalifa are not two things I expected to see in the same sentence, but here we are. Someone on the Internet (YouTube user theredsoxfan18) mashed up sad scenes from the Harry Potter movies (like deaths, parental memories, etc.) and soundtracked it with Wiz Khalifa's "See You Again." The result is... quite *sniff* emotional. Also: Wizard Khalifa, eh? EH? Okay.
Anyway, turns out theredsoxfan18 is a bit of a wiz when it comes to emotional mashups. See more here (including a Marvel x Evanescence one that I don't have the emotional capacity for currently). Also related: See Mr. Potter himself Daniel Radcliffe slay at rapping.
