"Maybe," Sam agreed, but he didn't really believe it. Jo had been entirely against lying low outside the tower, he doubted she'd be willing to lie low when it was under attack and she was in it. He just hoped she wasn't that badly off; he'd be kicking himself for it, even if he'd done everything he could to convince her to leave.
But he wanted to think positively about it, too. He headed towards the tower, determinedly. They would find her, one way or another.
He didn't know what her silence meant, but he didn't press it. Words might have helped him feel better, but that depended on what the words were. There were certainly some words that might not make anything better, at all.
As they approached, he let go of her hand, wanting to have both hands ready for a fight or to reach for his gun-- tucked into his belt, though he hoped he wasn't going to have to use it. But before he let go, he lifted her hand to his lips and kissed her knuckles, to make sure that she didn't misinterpret the gesture. No matter what they were facing, whether it was the possibility of armed agents or confusion over an ex-boyfriend, he wasn't planning on letting her go. Not easily, at least.
"Stay close," he said simply. "And it's probably just my paranoia talking-- but don't hang around the windows too much." He didn't know how much of the situation had been handled, but he really didn't want any nasty surprises.
