In his home country, Lucas gives a kiss as a polite greeting, and he's carried that custom with him to the United States. When he gets Jason confused with his twin brother Austin, it doesn't matter to him. He's cute, so he gets a kiss. Jason shows him some customs of his own, which includes some polite cock shaking, with a hard salute, leading to kneeling on bended knee, closed out by a proper bow while Jason extends more than just his olive branch.
