Autistic!Logan where Logan and Virgil bond over their shared traits :) !!
I mean the traits that often overlap between heightened anxiety and autism (anxiety, stims, sensory issues, etc).
Maybe after particularly stressful days, Logan retreats to his room and writes. He just,, keeps writing until he mentally tires himself out. Often times, this will cause his wrists to ache. He'll write anything; he'll write down his favourite words, he'll write script material, he'll journal, etc, just to feel the pen against paper.
Maybe Virgil goes to Logan's room, to ask him about something and see Logan writing, non-responsive to his name. His hand is writing at incredible speeds, not taking a break between pages as he mumbles incoherently to himself.
And maybe Virgil places his fidget cube on the paper, so Logan would notice it's presence.
Or Virgil wearing sunglasses one day and Roman makes a silly comment about it. Roman and Patton, being them, are too loud and Logan notices.
Maybe he takes them aside and talks to them about their volume, or takes Virgil to a quieter room (a soundproof/comfort room in the mindscape??) and just sits with him (or doesn't, if his breathing is too loud for Virgil).
I just,, Virgil and Logan talking about their experiences and sharing their tactics to help each other.
