Makes you wonder if there even is one, right?
So... Matt's picture and flashbacks show him in the cadet uniform, while shiro and his dad are in the instructor uniform... So assuming that cadets graduate the same time someone would graduate highschool... Does that mean Matt is lance, Keith, and hunk's age? I mean a sibling age difference of 3 ish years (pidge 14 Matt 17) is more common than like 6 ish years. He also looks young. Much younger than shiro... So... Umm... Shatt added to age discourse?
