Sam managed to grab ahold of the edge of the bridge with his right hand, and catch Maria's right hand with his left. Dean wasn't so lucky. He had plunged into the water below.
"Dean?" Sam yells for his brother. "Dean!"
"What?" asks a filthy and annoyed Dean as he crawls out of the water and onto the mud, panting for air.
"Hey! Are you all right?" Maria asks, just relieved to hear her older brother's voice.
"I'm super," Dean says, holding up the A-OK sign with one hand. Sam and Maria laugh.
"You know, I'm not sure I can help you up here," Sam tells his sister.
"Just drop me," Maria says with a small giggle. "I'll be fine. Disgusting like Dean, but fine."
"Are you sure?" Sam asks. Maria just nods. Sam lets go of her hand and she plummets into the murky water below. She comes up a few seconds later, muddy but unharmed, and not nearly as gross as Dean had been. She crawls out of the water and into the mud beside her older brother. They both make their way back to the bridge, occasionally sticking in the mud. Sam lifts himself onto the bridge and waits for his older siblings to join him.
Dean opens the trunk of the Impala and gets out two towels, handing one to Maria. They wipe the worst of the mud off of themselves. Dean takes Maria's towel from her and throws both towels into the trunk and shuts it. He then makes his way to the hood of the car, opening it up and checking for any damage that Constance might have caused to his pride and joy. He shuts the hood and leans on it after a thorough inspection. Maria joins him.
"Your car all right?" Sam asks.
"Yeah, whatever she did to it, seems all right now. That Constance chick, what a bitch!" Dean yells, as if Constance can hear him.
"Well, she doesn't want us digging around, that's for sure. So where's the job go from here, geniuses?" Sam asks, leaning on the hood next to Dean and Maria. Maria and Dean throw up their arms in frustration, and flick what's left of the mud off of their hands. Sam sniffs and looks at his siblings. "You two smell like toilets."
Early the next morning, Dean, Maria, and Sam check into a motel. Dean puts his credit card with the name Hector Aframian on the guest ledger.
"One room, please," Dean says. He and Maria are still filthy. Sam stands behind them, trying not to smell the dried mud still covering them. The clerk behind the counter picks up the credit card and looks at it.
"You guys having a reunion or something?" the clerk asks.
"What do you mean?" asks Sam.
"I had another guy, Burt Aframian. He came and bought out a room for the whole month." the clerk replies. Maria, Sam, and Dean look at each other.
Sam picked the lock to their father's motel room. He opens the door and walks in, hiding the picks. Dean and Maria are standing on either side of the door, playing lookout. Sam reaches out of the room and puts a hand on each of their shoulders, yanking them inside. He closes the door behind them. The three of them look around the room. There are papers pinned to every wall: maps, newspaper clippings, pictures, notes. Books on the desk, and junk on the floor and bed.
"Whoa," Sam says, surprised. Dean turns on a light by the bed and picks up a half-eaten hamburger sitting on the bedside table. He sniffs it and recoils.
"I don't think he's been here for a couple days at least," Dean says, as Sam touches the salt on the floor. He looks up.
"Salt, cats-eye shells…he was worried. Trying to keep something from coming in," Sam says. Maria has been looking at the papers covering one wall. "What have you got here?"
"Centennial Highway victims," she replies, still studying the wall, trying to make sense of it. Sam nods, coming over to her with Dean. "I don't get it. I mean, different men, different jobs, ages, ethnicities. There's always a connection, right? What do these guys have in common?"
Sam walks over to another wall covered in papers. There's a note that says "Woman in White" above a printout of the article about Constance's suicide. Sam turns on another lamp.
"Dad figured it out," he says. Dean and Maria turn to look at Sam.
"What do you mean?" Dean asks.
"He found the same article we did. Constance Welch. She's a woman in white." says Sam. Dean and Maria look at the photos of Constance's victims.
"You sly dogs," Dean says with a slight grin. Dean and Maria turn back to Sam.
"All right, so if we're dealing with a woman in white, Dad would have found the corpse and destroyed it," Maria says.
"She might have another weakness," Sam replied.
"Well, Dad would want to make sure," Dean added, he and Maria walking over to Sam. "He'd dig her up."
"Does it say where she's buried?" Maria asks Sam.
"No, not that I can tell. If I were Dad, though, I'd go ask her husband." replies Sam, taping the picture of Joseph Welch in the article. "If he's still alive. He'd be about sixty-four now."
"All right. Why don't you, uh, see if you can find an address. I'm gonna get cleaned up," Maria says, heading toward the door to go to their motel room. Dean nods and heads to the bathroom in their Dad's room.
"Hey, Dean? Maria?" Sam says. Dean and Maria stop and turn toward their baby brother. "What I said earlier, about Mom and Dad, I'm sorry."
"No chick-flick moments. Leave that to Maria," Dean says, holding up his hands. Maria scoffs at her older brother, sticking her tongue out at him. Sam laughs and nods.
"All right. Jerk," he says.
"Bitch," replies Dean.
"Asses," Maria finishes. Sam and Dean laugh. Maria and Dean both disappear, going their separate ways to get cleaned up.
Sam, alone in the room, notices a photograph stuck to the mirror in the motel room. It's a photo of John Winchester sitting on the hood of the Impala, next to a boy in a baseball cap on his left, a younger girl with wavy dark hair in her father's aviator sunglasses on his right, and an even younger boy on John's lap. Sam takes the picture off the mirror and smiles sadly at his family.
