Finn pressed his lips together. He would not have ever put himself at the level of Luke or Rey. Rey emanated with strength and came by force powers like they were nothing. Finn still thought of himself as a failed Stormtrooper; someone who was supposed to be part of a mass, not an individual, not some great force. He would also never ever admit any of that to anyone. Those were his dark thoughts and parts of the nightmares that kept him from any good night of sleep unless he was in one of his friend's bunks.
"I don't know. Rey seems to think I'd have a knack for it if I got any training at all. I tried to make a branch move so I could fight off those rabbits and it only wiggled." Finn fell quiet for a moment. "I just want to know, I guess. To understand what Rey seems to see."
There was no specific want to wielding the force. Finn only really wanted to find peace and protect his friends. He didn't require the power of the universe, but knowing that it did exist inside of him meant that he needed it to understand how he could get to that peace in his soul.
