Sam & Ruby/Claire - distracting Alastair.
He was having a hard time keeping memories from the past from floating to the surface. Him, sneaking into a house, looking for a demon. Ruby at his side. Walking right into a kill or be killed kind of situation with nothing but desperation and anger - lots and lots of anger - guiding his way. The only differences were that it was Alastair that they were hunting, not Lilith. There wasn't a clock looming over their heads, Dean wasn't pinned to some deal, and he wasn't entirely defenseless. There were differences here. And he, Sam, was determined as hell to make sure that the outcome resided within that very category. This would end differently. He would make sure of it.
Looking to Ruby, who was carrying Claire's body (he wasn't going to get over how odd and uncomfortable that made him feel), Sam quietly pressed a finger to his mouth and pushed the door to the house open. It was getting dark, so the shadows that played their way across the walls of the house made his entrance that much more cautious. When he was certain that they weren't going to get jumped on sight, Sam slowly stepped into the house, his gun stretched out in front of him while he strategically inched his way to the nearest wall for cover.
Motioning for Ruby to do the same, Sam glanced back into the first available room and scanned the area for any signs of life. They had to get the jump on Alastair. That was what this plan was all about. So long as Dean was careful enough to keep out of the way until they found him, this would work. It had to. It'll be different, he assured himself, Dean's gonna be fine.
