You were a weak padawan learner during the clone wars, the absolute bottom of the spectrum, having barely any control over the force. But that all changed during the battle of Geonosis, when you had watched your Master be struck down by a blaster bolt from the hundreds of droids sending lasers your way. In that moment, you forgot about the Jedi way, becoming consumed with anger and hatred at everything; not being able to use the force well, losing your master, the stress of training. It all came crashing down and you slammed your hands into the ground, sending out a shockwave that knocked down droids and clones alike, and got the attention of the more powerful Jedi.
