While Meri had purposefully not given John a weapon - particularly as she still wasn't completely convinced he even was John - Meg had no qualms about it. That might seem strange, considering she was the only one in the car who wasn't related to the guy, and he wasn't exactly her biggest fan to boot, but frankly she wasn't all that worried about him shooting her. He could, of course, but he'd only wind up facing Jack and Meri's combined wrath if he did. And she'd like to think not even John Winchester would be that insane.
Either way, though, he deserved to be armed, as far as she was concerned. Not to mention, if something happened and their backs got against the wall, he was a damn good shot to have in their corner. So it just made sense. Even if she couldn't resist goading him a bit when handing over the weapon.
"Don't worry about us, Jack," she replied, tossing John a wink before pulling a gun from her waistband. "I'm sure we can find ways to entertain ourselves back here. You just get us there." Then she held the gun out for John to take, tossing him a wink before pulling another gun out with her free hand and half turning in the seat to make sure they weren't being followed.
As it turned out, neither she nor John ended up needing the weapons for the ride, but Meg didn't insist on getting the firearm back when they arrived either. Instead she was half-starting toward the doors to the safe house only to stop suddenly when Jack trailed off. With a concerned look that was hidden with indifference, unless you really bothered to look, she turned back to the rest of them. By default, her attention slid to Meri because, where Jack was concerned, very few made a move without making sure Meri was on board. That was how you wound up shot.
Meri, however, looked for her part as though she was barely hanging on. Extremely pale from blood loss, her entire side soaked with blood, and with at least a few broken ribs and probably a concussion, she wasn't exactly firing on all cylinders. In fact, she simply leaned up against the side of the car, her silent and pensive gaze locked onto the ground in front of her and her hand reflexively opening and closing into a fist and back again. Meg sighed softly then drew in a sharp breath.
"Well, I don't know about the rest of you, but standing around out here all night really isn't doing it for me. Jack, Meri, you both need to get checked out and I already said Adam was looking for you. Now get your asses to triage." She paused, her tone hardening even more. "Move it."
Almost instantaneously, Meri seemed to respond to the order. Snapping out of whatever shutdown her mind was attempting to have, she nodded her head once, sharply, then grabbed hold of Jack to help him - and, by proxy, also help herself - get inside. She cast a sideways glance at John, brow furrowed slightly as though finally seeming to realize he was actually standing there. "It's not right," she stated in a low, somewhat numb-sounding, tone. "Out of anyone from your time who could show up here, why'd it have to be you?"
And with a shake of her head, Meri turned back to her brother and the task of getting them both inside to relative safety. Meg, meanwhile, sighed once more then turned her own attention to John. "I will say one thing about you Winchesters. When you have your issues, they are definitely some damn issues," she muttered. Then she tipped her head toward the building. "Come on. Let's get the reunion over with already. Then we need to see about tracking down Gabi and getting you chipped."
