She didn't really come clean but the reaction was pretty amusing as it was a reaction that lined up more with a YAB on screen than say if she was young. Ember also mentioned playing League in Season 1 (which was 2010), however she has had an in joke that she is around 30 or in her early thirties. Its of course possible that Erina was leaning into the bit, but her thing has been the "zoomer" of Phase which seems kind of off if we are going from a minimum 26/27 year old range.
