The thud of Sam's axe hitting the wall joined Dean's own, doubling their efforts at tearing into the closed off building. Taking advantage of his largely built figure, Sam swung at the wall hard and quick, desperate to tear away each and every bit of plaster and wood that separated himself and his mother. Even though things were very much tense between the Winchester men lately, Sam had to give his brother and father credit where it was due: they still knew how to work together, even without having to come up with an actual game plan before striding into the fight. Dad knew to keep guard; scan the perimeter, make sure nothing was coming at them from behind, above, or even right in front of them. Dean knew to work hard and fast, too; attacking the wall with the same level of ferocity as Sam, knowing that there wasn't a single moment to waste. They may not have particularly liked each other a terribly large amount right now, but they were still a team and they knew damn well how to act like one.
It seemed like Sam and Dean were finally making a little progress at tearing through the wall - a hole was finally beginning to break into sight - when Sam heard it. Not it - her. His muscles tensed, axe pausing mid-swing. Who's there?
"Sam," he immediately started. Sam shot Dean a pointed look, putting a hand out to indicate that he needed to stop swinging for a second. At that, Sam pressed in closer to the wall. He tried to peer through the hole that they'd created, but it wasn't big enough for Sam to see through yet. There was just black - bits and pieces of wall still blocking off the way to the other side, probably. That didn't mean that they hadn't done enough damage for Sam to hear and speak through the wall though, so he pushed his ear to the surface and immediately began to speak in a hurried tone. "It's Sam," he repeated, a little more loudly. "I'm here with Dad and Dean." His heart tugged in his chest anxiously, every bit of his being demanding that Sam ask if she was okay. Was she hurt? What had Azazel done to her? Was he in there with her? No, Sam realized. He couldn't have been, he wouldn't have let her speak, let alone approach the wall...unless he was trying to screw with them? It wouldn't have been the first time. Maybe he was really talking to Azazel right now. Sam didn't know. Fortunately, Dad was still standing behind them with his gun trained upward, ready for anything unpleasant that might break out of that wall. Sam trusted that he knew to keep it that way too, even in spite of the voice that they were facing now. They'd just have to keep working and hope that it really was Mary Winchester on the other side of that wall.
Sam hadn't prayed in a long time. Once Uriel and Zachariah had touched down to show the world what angels really were like, Sam had stopped. Discovering that he had spent his entire life praying to a bunch of douchebags with wings had been the end of the line for him. No more prayers, no more questions of guidance from God - nothing. But now...
If there really is someone out there looking out for the little guys like me down here, Sam thought in a panic, please. Let this be her. Let her be safe.
"Get away from the wall," he said sharply. "We're breaking through." Then, with a strong sense of determination glinting in his eyes, Sam dragged his axe over his shoulder and swung at the wall even harder.
