Dean glared at the annoying intruder standing on his bridge.
At the weapons console, Samsquatch clenched his hands to control his own fury at the fact that none of their phasers would have the slightest effect. This was actually much more restraint than any of his fellow Klingons would have shown in a similar situation, but Samsquatch wasn't like other Klingons. As a baby, he had been the sole survivor of a Klingon outpost decimated by a pirate attack. John Winchester had rescued him from the rubble and when no other foster family could be found, had brought him home for his wife Mary to raise along with their own son Dean. Growing up amongst the more fragile humans had caused Samsquatch to learn to moderate his temper, although on those occasions when he did cut loose his Klingon size and strength made him a formidable opponent. Dean and "Sam" were close, as Mary's untimely death and John's frequent absences on missions had forced them to rely on each other and become brothers in the truest sense. When Dean followed the family tradition and joined Starfleet, Sam came with him. Dean was fiercely protective of his much larger baby brother and made sure they were always posted together, as throughout his life Sam had been faced with prejudice from those who feared his Klingon blood.
From the science position, Cas-TL calmly stated that their forward momentum had been abruptly suspended. From his captain's chair Dean wished Cas could just say they'd stopped. However, Cas-TL was an android, and while he might look almost human (except for his glowing blue eyes), his stiff posture and lack of social skills betrayed that he was not. Dean had been frustrated on more than one occasion by his profound literalness.
Dean and Sam had first met Cas when they were all assigned to a mission to locate a power-mad tyrant and thwart his plans to start a galaxy-wide war. Dean hadn't been too sure at first about the odd little android, although he could see that his superhuman strength, inhuman reflexes, and encyclopedic knowledge going back seemingly to the dawn of time were all advantages. Sam in contrast seemed more accepting. Cas had proved himself on a number of occasions during their arduous mission, saving their lives so many times Sam had dubbed him their "guardian angel." Ultimately, Cas had even disobeyed Starfleet orders to help Dean save Sam. That act of rebellion had cost him his Starfleet commission and almost cost him his life when he was disassembled by a blast.
Dean and Sam resigned their commissions when they learned that certain factions within Starfleet had been working to try and bring about the war for political reasons. They felt they could no longer give the institution that their parents had revered their full loyalty. When Dean learned that his father's first ship, the Impala, had been decommissioned, he used what influence their successful completion of the mission had gained them to obtain title to the ship. With the help of a family friend who owned a salvage yard, they made some upgrades to the ships engines and weaponry to prepare for their new self-appointed mission. While disillusioned with Starfleet, they realized that there were many small colonists and spacefarers who often fell through the cracks of official protection. They could use the Impala to try and fill some of these cracks, fighting off pirates and perhaps preventing another massacre such as the one that killed Sam's Klingon family. When the refit was finished, Dean realized there was really only 1 other person he would trust to join their crew. So while Sam took his usual position on Dean's right side, Cas now filled the position on his left. This would give Cas the opportunity to search for his missing creator while helping Dean and Sam. Cas' own personal mission was to try and become more human. Toward that end, Dean had decided that he was going to help teach Cas humor and finally get him to smile. Sam often bemoaned his attempts and said Dean himself needed to learn appropriate humor.
The three of them had been successful in their endeavors to date. Their combination of strength, intelligence, nerve, and a big dose of crazy allowing them to overcome seemingly much stronger enemies. Yet now before them stood a foe they were almost powerless against. They had encountered G before, and the meetings had never been good. Dean had heard G described as "kin to chaos" but he thought the description "weapon of mass destruction" was more fitting. G claimed that his tricks were performed to teach people lessons, but Dean didn't buy that. He still held a grudge for a particular lesson G had for Sam which seemed to require G killing Dean. Repeatedly. In some very bizarre ways. In another lesson G had thrown them into an alternate universe where they were forced to play the parts of famous fictional characters. That one had been just plain embarrassing. So now as G stood smirking before them once again Dean wanted nothing more than to punch him in the face. Instead he looked over at Cas and silently gave him the go ahead. Cas activated the ring device in the floor, trapping G in a force bubble. Cas had searched his extensive knowledge after their previous encounters to find a way to neutralize the powerful alien. Now that they had him, Dean wasn't sure what they would do with him. Although he might make an amusing hood ornament…
