"Humans don't live for centuries! We can't wait for progress." Jayce is an ambitious, somewhat gullible (in earlier episodes), and creative person. In Act 1 of Season 1, he has a dream for Hextech and is confident in its potential. He has a passion for his invention and when he and Viktor successfully harness the Hex crystal, we see a child-like happiness from Jayce. Later in Season 1, he becomes less gullible as he makes his way up to be the de-facto leader of The Council. He is more strong-willed with his decisions in politics. We also see his caring side when Viktor grows more sick, and he leaves Mel’s bedside to be with him.
