Wait, the whole point of my post was that they are all teens due to the official synopsis of the first Voltron comic that came out a few days ago. But for clarification, someone spread the rumour that ages were confirmed on the panel (with Shiro being 25, Pidge 14 and everyone else in their late teens), /but/ actual participants of the voltron panel said that this never happened, that the age question wasnt discussed in the least. But now this misinformation spreads like a wildfire and people are insistent that this is canon, even if it is not!
So yes, they are all still teens (I posted the screenshot of the comic synopsis somewhere but I’m currently on mobile. Should find it quickly on ‘yuufa talks’ tag if I didnt forget to tag it as such!)
