Well, Before the infamous speech from Uncle Andy, Nancy(Shane(the kid's)) mom tried but failed miserably to talk to him about it, So she passed it off on Uncle Andy, Who said to her when asked "I'm all over it."
This is from Season 2, Currently Season 5 has just ended with Season 6 in the making.
And let me just say, Shane is growing up awfully fast, From the time he holds a knife to some asshole's throats and tells them to get out, To when he gets shot, To when he----no, wait, watch the last episode LOL
