Why does it have to end like this?

Where Did he go?

When I woke up in the next morning, I heard a noise downstairs. I got up and grabbed the gun and salt rounds out of my drawer, just in case. Dean was already down there, well I think because he wasn't in bed. I walked silently down the stairs and saw Dean making breakfast, burnt pancakes and under cooked eggs. I let out a small laugh and walk up behind Dean to try and startle him. I put the gun on the table and grab Dean's shoulder "BOO" I say. Dean turns around expressionless, and gives me a quick smile. "You know you can't scare me right?" He says almost mockingly. "Yeah, yeah, shut up" I say smiling at him. The TV is on in the living room with Jason sitting in front of it watching 'Despicable Me'. 10 minutes later I call Jason to the dinner table to come and eat. Jason got up and ran to sit down. He looks at the black hard pancakes and frowns. "Mommy?" He asks "Why are we eating over sized pucks?" I almost choke on the milk I was drinking. "Jason" I say trying to hide my smirk. "Daddy made these and we are going to eat them." Dean picks up his pancake and hits as hard as he can against the table, the pancake doesn't break but the table dents. Deans eyes widen and he collects the pancakes. He puts the pancakes in the garbage and picks up the Impala keys. "Who wants to go out for breakfast?" he asks. "ME" Jason squeals happily. I laugh as I get up and clear the plates up and put them in the sink. I pick up Jason and bring him upstairs to get him dressed. He picks out a dinosaur shirt and jeans. I go to my room and put on a blue tank top and blue skinny jeans. I head downstairs's ready to leave. "Ready to go?" I ask. "Um... Wheres Jason?" He asks puzzled. "Oh I thought he came downstairs." I say, "I'll go check up stairs" I run upstairs and check Jason's room. Not there, I look all over up stairs starting to worry,. "He's not here!" I call down to Dean. "SHIT" Dean yells out. "He's not down here either" He calls back up to me. I start to look upstairs once again "Listen here you bastard!" I hear Dean call. I run downstairs at full speed. When I reach the bottom, I see a demon with Jason. "YOU LET HIM GO!" I yell at the demon I run forward only to be stopped by Dean. The demon looks at me with a crooked smile before snapping her fingers and disappearing with my little boy.  I fall to the ground crying feeling as if I've lost everything. "This m-must be...a...dream" I say between sniffles" I close my eyes tight and Dean hugs me close. "Not a dream baby,not a dream." he says with tears in his eyes. "Where did he go?" I repeat to myself as I cling onto Dean. "We will find that son of a bitch, I promise" Dean says with anger and sorrow. "I promise" He repeats.
