Dean Winchester was a genius.
Samsquatch and Cas-TL might argue that they had done all the actual work, but it was Dean who came up with The Plan.
They were cruising along with no particular destination in mind when they received a communication from Bobby about trouble erupting on a small mining colony. It was hoped that they could get there before too many lives were lost. The Impala took off at maximum warp and made it to the planet in record time.
The problem was, the colony was currently surrounded by a huge ion storm. In addition to the dangers of the storm itself, dilithium debris caught up in the maelstrom made landing almost impossible. The dilithium pieces could drill right through deflectors already stressed by the storm and pierce the ship's hull. The crew was frustrated to be so close and yet unable to reach the colony to help.
It was then Dean had his brilliant idea. Sam and Cas were initially stunned into silence by his awesome plan. Once Dean assured them that he really was serious, the two huddled by the main computer, tossing ideas back and forth while scrolling through schematics and sensor logs.
Dean lounged comfortably in his captain's chair and surveyed the results of the collusion with satisfaction.
The force bubble surrounding G siphoned off his own immense power to keep him contained. It could easily withstand the storm and repel any dangerous debris. Increasing the size of the bubble was also no problem with such a power reservoir to draw from. So the force bubble (with G inside) had been maneuvered and expanded over the forward deflector and anchored in place with tractor beams. The resulting buffer it provided meant the Impala could approach with no problem.
Dean gloated. Payback was a bitch, and G did make an awesome hood ornament.
