Uh.... everything here pointed to him gaining a new power at this very moment. If you recall, we have received flashbacks of 'training' as well and this time we just got a flashback of a mere conversation that triggered some higher sense of responsibility. If portrayed properly, then the older flashback would have a been a motivator for a training flashback where he learned how to use it before feeling some backlash from particles.
