i have so many thoughts about dghda and age, first off the blackwing gang(TM) never realy understand it (eg. vogel saying he can be amanda's grandson) and ALSO
since we don't have the official ages of the blackwing folk, this is what i feel each character gives off (and i'm not counting francis, bcs we know how old he is and he's def the oldest)
first we have the OG rowdy 3, who are probably around late 30s to 40s
then i actually think mona could be older too. think about it, she's literally a shapeshifter so is technically ageless.
y'all know i'm obsessed with dirk/mona being found family siblings, that's why i think mona would be older than dirk/bart/vogel. idk dirk just gives off younger brother energy, and i think because of that mona did a lot to protect him in blackwing, yk bcs she's like a god essentially. bcs of this i always saw her as an older sister type, bcs i feel thé sheer power of her was so often used to protect dirk in blackwing.
now i'm like a firm believer in dirk and bart being the same age. like, their abilities parallel eachother so much it makes sense if the universe decided to drop 'em both onto earth at the same time (i would even not necessarily doubt bart and dirk being biological siblings, but that's just a bit too off canon for me to fully adopt dkfjdjf)
and then i think vogel is def the youngest, just because (iirc) riggins/preist/freidken/someone mentioned that when vogel joined blackwing was when the project became too unstable, causing the initial breakout. so clearly, there was alot of time before vogel joined.
again obv just a theory (a GAME theory) and i would gen love everyone else's thoughts
