Sword Art Online II Episode 3- Development and depth? In SAO?

So my question from last episode is answered and I will honestly say that I expected this sort of problem that Sinon, or rather, Asada Shino is facing.

So just because of actual backstory and having a motivation that goes beyond just playing a game instantly makes her a more likable character then nearly everyone in the cast already. What wonders backstories and actual motivation do to a character eh? However, that’s not saying much since Sinon will inevitably fall for Kirito instead of the nice, considerate guy who showed up this episode.
