Kon remembers mmmmost of it, in a sort of dreamlike way, where he woke up from it and thought about certain parts of it too hard so he hasn't really forgotten what was in it like he normally would. The parts that didn't grab his focus are fuzzier though, and overall he has much more emotional detachment from it, though knowing the Sekirei mark was real on Takanari gives it some weight.

He'd really be a lot more indifferent to Zack if not for the game. Zack isn't really the type of person that Kon would approach, since Kon is really more interested in intellectual types and people to engage and fight with a little. Because of the game he tolerates Zack way more than he would otherwise XD; and is giving him a chance to spark his interest. He's also way more tsun at Zack than he'd normally be with people.

If Kon had less Sekirei, would he have gotten jumped?
