Hunter x Hunter 2011

I just assumed the whole thing happened in that .5 seconds Kurapica said he needed them distracted for.

What other villains has the series actually had so far besides Killua's brother?

Well, there's also Hisoka. I think we've seen the extent of what we'll be shown from them and their past. We've really not seen anything to the contrary with any character in the series, not even our heroes. I don't expect anything more than a few hints here, a few seconds of flashback there just like we've done until now.

But who knows, I may be wrong, but it doesn't seem to fit with the structure of this anime which is more present and dialogue oriented.
