I asked Johanna once if she'd ever loved someone before the games.
She told me she loved her family, when they were still alive and I thought she must have misunderstood the question on purpose.
"No, I meant. . . ."
"Like you and Peeta? Annie and . . . Finnick?"
"Yeah."
"No, I never did."
I noticed a subdued tone in her voice and though I knew I must be overstepping my boundaries, I questioned it.
"You're sure? There was never . . . anyone?"
"No, Katniss, there never was. I wasn't interested. I'm still not."
I don't push any more after that. I understand what she means.
Like I said: very short. I may continue these; I certainly have enough headcanons to make a few.
This headcanon - Johanna Mason = asexual aromantic (implied - Katniss Everdeen = demisexual aromantic)
