Gladion: 13
MC, Lillie and Hau: 11
This can be inferred because Wicke says that both you and Hau are 11 and her dialogue implies that Gladion and Lillie ran away when they were 11. It's only been 3 months since Lillie ran away so she is still 11 and it's been 2 years since Gladion ran away so he is 13.

Pedo.

Gladion's ass must be puffy
I don't remember her ever saying Gladion was 11 when he ran away.

why and how?
I wish I had had friends like this when I was 11

She said that all kids leave home to do when they need to do at 11 so it's implied. The Japanese version also confirms Gladion is older than Lillie.

>I suppose all children must yearn to take a journey of their own choosing when they get to be about your age.
Wicke was clearly referring to Gladion and Lillie with this dialogue.
