From State of the County. This one's a little more subtle than some of the others.
No matter how crazy a thing he's doing, no matter how stupid a plan he's got cooking, Bo is always right behind him. When he goes taking life (and liberty) for granted by sassing the local law, Bo is behind him one-hundred percent, except when he's in front of him. When Jesse's tax payment goes missing, and Luke's got to bend over the General's door frame to search for it, Bo's right behind him then, too. Which just goes to show that having Bo behind him isn't always a good thing.
But when bombs start blowing up everywhere, he wants Bo behind him, wants him turned sideways and low, keeping all of his vital organs protected. Wants Bo behind him, or maybe back safe at home, when Rosco starts waving his gun, when Boss starts accusing them of being responsible.
Hiding out at the lake, nothing behind him but the General's windshield, he watches Bo toss stones into the water. The boy's never mastered the art of skipping them, and wouldn't have the patience now to do it right, even if Luke showed him again. Besides, how Bo throws is not the point. That he's free, and that he has all ten fingers, than none of them have been blown off by randomly exploding bombs, that's the important thing.
Bo's behind him when they try to broach the idea of Earl's involvement in the violence to Daisy, too, even pipes up, despite the fact that he's ill-prepared to break a woman's heart. Luke's an old pro at that kind of thing, and Bo could leave him to it now, but he doesn't, because he's behind Luke all the way.
Luke has to let him go, too many things need doing in such a short time; he can't keep Bo behind him for this part. He sends Bo away from the bomb, though. If he can't tuck Bo safely behind him, at least he can send him in the opposite direction, after Daisy and Earl. Still, soon as Boss is tackled away from immediate danger, Bo pulls him back like a magnet, into the General and off to the rescue.
Bo's behind his decision to stop chasing Earl, too. Not right away, but he comes to see the wisdom of it when Jesse chimes in with his two cents. Bo's right behind him in hugging Daisy – holding her up, more like – after the crash, while she's marching this week's wrong guy out of the brush.
Bo's been behind him all through this mess, and now that it's over, Bo's still behind him. Sweet smelling here where the ground has recently thawed, cool breeze on his neck, and Bo's right there with him, there on the wooded edge of the creek that runs across the farm. Standing back there and waiting for an answer. Luke, what's eating at you was where he started this conversation that isn't, and now he's doing a relatively good imitation of being patient.
What's eating at him is that Bo will follow him anywhere, right behind him. And where Luke wants to lead…
There's an arm around his shoulders then, and Bo's so close behind that Luke can feel the contour of his shoulder, ribs and even his hip down there, a not unwelcome feeling.
"You know," Bo says, and Luke can hear the warmth in his voice every bit as clearly as he can feel the heat of his long body. "Whatever it is, I'll be there right behind you."
That's exactly what Luke's afraid of.
