Sam was no foreigner to that false smile that Dean immediately slapped onto his lips. Other folks might have bought it, sure, but not him. He knew Dean too well to believe that he was just fine and dandy - not now, he couldn't be. Neither of them were. Half of him wanted to reach out and confirm that Mom was still in there alive (for now) according to Chuck and his visions, but Sam didn't want to screw this up. If they did find Mom alive and she didn't make it out the door, what use was telling Dean anyway? He would have gotten his hopes up, only to have them crash back down at his feet. Dean didn't deserve to have his emotions toyed with more than they already were, so Sam didn't mention it. Instead, he carefully took the axe that Dean passed over and looked down at it quietly. They were going to have to hack their way into that building. There were no entrances. No windows. It was just one giant box, which made Sam wonder: could Mom even breathe in there? Sam squeezed at the axe handle, decidedly turning for the building. They had to move.
Couldn't move without Dad though and he was only just turning into the scene. Sam tried not to glare too hard at the sight of him - the last thing either of them needed was to get into another argument when they had more important things to deliver on. Still, Sam couldn't help the sarcasm that bled through when he decided to speak to the man. There really was only but so much that he could hold back. "I thought breaking our way in, getting Mom out, and beating Azazel down sounded like a pretty good idea," Sam said shortly, fingers twisting against the axe handle as he spoke. They really needed to move. "Look, if he's there - just, focus on getting Mom out. I'll distract him." Sam didn't want to give either of them the chance to protest his suggestion. It made sense to Sam. Azazel always did have that twisted fascination with him. If Sam pretended to be awestruck by his blood or if he even went at him and attacked him alone, that'd give them enough time to get Mom out the door. Sam didn't have much of an escape plan for himself set into motion yet, but he'd figure something out when the time came along. Hopefully.
Turning, Sam reached into the back of the Impala and pulled up some holy water. It wasn't one of the big containers that they had buried back there, but it was enough so that Sam could effectively use it against Azazel or any other demons that were waiting for them when they got inside. He tucked it into his jacket, then looked at the duo standing beside him. They were still wasting time. Sam knew that being reckless wasn't the way to go about things, but this was their Mom that they were leaving at risk. For all he knew, Azazel could be in there right now. Hurting her. Making her suffer. Making her - "Can we go? Now?"
