I thought that in the manga when Grisha showed up, it was after the ritual when the royal family pass down the founder Titan, 3 years is more than enough time to master Titan form look at Eren, he mastered his form and even hardening in like 6 months before they met again with Keith Shadis as Keith says "it's only been a few months since you guys graduated but you all seem like different people." I think Frieda has just became a Titan shifter when Grisha showed up.
