Sam and the Sarcastic Ghost of the Merchant Estate

Chapter 1: Sam's Bad Mood

Sam was in a terrible mood, he was fed up with all the monsters, witches, demons you name it and Dean being like 'hey Sammy let's go on a case and not get murdered', he rolled his eyes and went downstairs to the map room muttering angrily to himself.

He sat down and sighed as Dean and Castiel were cleaning weapons and reading lore books, just regular hunting things as Sam was still in his bad mood muttering "I just wanted to have a good day but nooooo dean just had to ruin it by going 'hey sam lets go on a dangerous case and not die' he's such a jerk".

The angel looked at Sam curiously "Hey you okay Sam you look angry about something" Sam scoffed and said "I'm fine Cas don't worry" Dean looked at his angry younger brother "looks like someone got off the wrong side of the bed" he chuckled but Sam just rolled his eyes again and said "Whatever". Castiel looked concerned but then said, "we got a case if you wanna join?" Sam just sighed and said "what's the case," he asked plainly.

Dean looked at the case and said "A family got killed in a house and are still haunting and killing anyone who goes inside to stay the night" Sam just thought 'great I'm going to die with my idiot brother and his angel boyfriend fantastic'

Sam said stiffly "I'll be getting stuff from my room," he said getting up to leave "okay Sammy" Dean replied as he saw his younger brother leave to go to his room.

Castiel looked at Dean and said, "Dean why is Sam so angry?" Dean just shook his head as he put down the rifle he was cleaning on the table. "I have no idea Cas, maybe he's in a bad mood?" he shrugged and Cas sighed deeply.

Sam was in his room getting supplies and mumbling angrily when he felt a bit weird, he ignored it and went downstairs and said "Alright guys let's get this done" he sighed deeply and they got into the Impala and drove to the mansion as dean told him where they were going.

As they drove to the mansion Sam was listening to music and sang to himself, Dean heard him and yanked an earphone from sams ear and said "Not a bad singer Sammy" he said grinning, "Thanks dean" he said sighing. "Are we nearly there?" the angel asked looking up from his book "nearly and here we are!" Dean replied. 

They pulled into the drive of the mansion, its massive figure looming over them. Dean and Castiel were in awe while Sam rolled his eyes and scoffed as his bad mood worsened. They went inside and looked around. Dean was fangirling about the house cause he loved old haunted houses. 

Sam looked around the upstairs while Dean and Castiel looked downstairs. as he looked around Sam felt like something was following him, but he thought it was nothing. He carried on looking around and felt a headache creeping in his head "ugh...my head what the-" he saw a ghost mumbling sarcastically to himself and saw Sam as he mumbled "Great! I've now got a headache this couldn't possibly get any worse" The ghost turned into a swirl of pale blue mist and wrapped itself around Sam and went up inside his nose as he breathed it in, then he felt different as the ghost possessed him his eyes glowed a pale blue, he saw Dean come up the stairs and his eyes turned back to their chocolate brown. 

"Hey Sammy find anything," he asked his younger brother, "No dean what do you think I am a ghost detector! Seriously god" he rolled his eyes and left his brother standing there confused as his brother walked down the hall. Cas walked towards Dean and looked confused "why was Sam so sarcastic?" Dean replied "I have no idea cas I'm kind of thinking something's wrong with him" Sam was walking down the hall still pissed off, he felt his bad mood worsen but he ignored it. 

Dean followed his brother down the hall, hearing him rant for some reason, The angel followed " I'm sensing something's off with Sam it's unnerving"  Dean nodded "yeah he's never this sarcastic like ever" Meanwhile Sam was ranting and being annoying. 

Dean and Cas followed Sam as he ranted off about everything, he just felt like he needed to rant about everything, they got very worried about Sam, as he had never been this sarcastic before and it was unnerving so they decided to figure it out and if that didn't work, get Rowena or her daughters, as they were all really powerful and could help, but they decided to see the changes happen to Sam and see how bad he would get overtime.
