Gibbs knew they were both there before Abby said anything. "Permission granted," He paused to take a sip from the jar, before he added, "Both of you." He wasn't gone yet. He still had his head, so his words weren't slurred. Setting the make shift glass down he began to run the hand plainer down over the top of the deck once more.
He mopped an arm over his brow, brushing away sawdust and sweat. Shifting in his seat, so that he straddled the boards. He cast a glance at Abby. He knew she knew. He wasn't sure about Robin. He'd already poured a 'glass' for Mike. The proverbial bow. After a moments thought he pushed himself off of the boards. Striding over to the work bench he emptied two more jars, wiping them out, he splashed some bourbon into each. Not quite sure he should offer Robin any or not, considering, but Gibbs figured he'd know if he could drink just one or not without falling off the wagon. Without another word he offered each filled 'glass'.
