I loved this episode so much like I can't even express how much I loved it
Spoilers for 1x13, "Large Blade."
Jack groaned, bringing a hand to his head. It was throbbing, and blood trickled slowly from the cut on his forehead. The brunet bolted upright as his memories suddenly returned to him, and he realized that he was still trapped in the helicopter, along with Cynthia and MacGyver. However, Viktor was nowhere to be found.
Jack shook his head briefly, regretting it almost immediately when the throbbing in his head increased, but the sentiment still stood. The agent had bigger things to worry about than where the convict was at the moment.
After struggling briefly with his seatbelt, Jack managed to unlatch it and stood. The space was cramped and he hit his head as he tried to rise to his full height, but the man brushed the minor annoyance aside as he realized that there were a few flames around the helicopter. He stiffened as he realized that there was a chance that something vital could catch fire, causing the helicopter to explode.
The risk was small, but it was there.
Jack immediately turned to MacGyver. The kid's seatbelt was stuck, and the blond was slumped against the side of the helicopter, eyes closed and a worrying lump rising on the back of his head. The brunet crouched by the seatbelt, keeping a close eye on the flames as he worked at it.
The man heard Cynthia groan, and he increased the urgency of his efforts.
Finally, the buckle gave. Jack grabbed his friend under the armpits and pulled him to a safe distance from the wreckage. Then he turned back for Cynthia. As he began to work at her restraints, he saw MacGyver begin to stir out of the corner of his eye. Swallowing the urge to shout in relief, Jack merely urged MacGyver to come help him release Cynthia.
They were trekking through the forest when Jack allowed himself to think about his actions in the helicopter. He should've gone for Cynthia first, as she was obviously the most injured. At the very least, protocol dictated that he should've checked her before trying to get MacGyver out of his restraints.
Jack frowned to himself. He knew protocol. He was trained to follow it, had followed it for many years. It had saved his life more than a few times, as well as other's lives. So why hadn't he followed it here?
Jack's answer came to him as he watched the young man in front of him help Cynthia over a particularly bumpy patch of ground. He would bend protocol, break the rules, heck, even go against the law to protect the blond. And he knew that MacGyver would do the exact same thing for him.
That's what brothers do.
