The information that Shannon had been married caused Jay to get scared half to death.
"Shit, for reals? Married? You don't look the type to get hitched!" Why did anyone do that, anyway?! Although he probably wouldn't oppose to marrying Justice, but she wasn't an option for another couple of years. Or ten.
Shannon kept talking about knowing herself and whatnot and Jay just really thought she was getting hotter by the minute. And he was getting horny. What a fucked up thing.
