I'm re-reading your Avengers Games AUs for the hundredth time, and got across the Blake, Rowan & Lyme fic. It hints at Blake and Rowan backstory with Frigga, and I can't find anything on LJ. Did you write anything about it by any chance?? It sounds superrr interestingggg...
so in the normal universes the trainers pull rowan & blake aside and give them the priorities talk (TM) and rowan says he wants to leave but blake gets terrified that it's a loyalty test and if they both try to leave they'll get killed so he agrees to stay
rowan is of course heartbroken and betrayed by this so they don't get back together once blake ages out (in the main au - in canon there's, you know, The War and it's more complicated so they might, maybe)
(there's some stuff i retconned later, like originally i thought blake was bi and eventually got married to a woman and had a kid -- he ain't! he's super duper gay lol. rowan is extremely bi though)
IN THAT SPECIFIC AU (the brutus and frigga get married one) frigga is a trainer and she sees the rowan and blake thing happening and is like, oh boy, so she convinces blake that this is not a test and they will not kill him / rowan if he says no, and asks him, again, if he wants to leave. he does. he very much does.
so in THIS universe he and rowan both get to leave and go home and reunite and cry and eat popcorn and make a blanket nest and have a weird teen regression because they, you know, sort of got adrenaline-trauma-teen-married at 15 while murdering people and now need to figure out who and what they are as normal ("normal") people
which is not... normal, they decide they're all in on the teen married thing (not actually married bc rowan's parents are sane and say no lmao but i mean. basically) but they get to be kids for a bit anyway
