RE: Hawks using "Touya." Taking into account that he used "Dabi" during the pre 2nd War strategy meetings (where I'm pretty sure Endeavor was absent), and referred to him as "Dabi" in his head in the chapter just before the panel/line you posted, it always read to me like he was using it just to be considerate of Endeavor feelings and/or not to be confusing. (Endeavor is also "Todoroki" after all.) Which of course leads me to imagine that post war he'd politely call him "Touya" in front of Endeavor, but then pettily switch back to "Dabi" the second Endeavor's out of earshot. lol
Oh I love that lmao
Hawks would def be that level of petty and more after everything, and if they do ever interact again, that's what I'm looking forward to
literally no better feeling than blurting out some loud dumbass joke with your buddies and hearing a total stranger ugly-snort-laugh as they walk past bc their own laughter caught them by surprise. find joy and connection in the spontaneity of strangers you son of a bitch. i fucking got your ass
