Is Syrio Forel the same person as Jhaqen H'ghar? I suspect he is, because A: they're both from Braavos, B: they're both totally badass, and C: they can both kill a bunch of dudes. The internet seems to have a boner for the idea that they're the same person, as well.
Keep in mind I haven't read past page 200 of A Storm of Swords, so it's not like I've read a ton of the series.
