dantes and oberon beating each others' ass over their Highly Dubious Ways to Care for guda vs edmond "my fate, my destiny" dantes and artoria "master is my life" caster doing a tiny fist bump of mutual understanding
i think i love the thought of a cigarette kiss for edguda but at the same time... kinda not ww as it feels like, that's something Servant: Avenger Class Guda would do... as it means they've truly succumbed to hating just as much as they love. and in hating, that means they've given into their desires to kill those whose killed their loved ones, finally taken true revenge and given into the flame that they had every right to claim, to the flame that would make them the same as the Count of Monte Cristo... so its really fitting that guda remains as someone who 'lights the Count's cigarette' instead of sharing a smoke with him... i still think it would be romantic but nothing beats the classic of "I'll lend you a fire anytime, my Accomplice." and they're the one who lights his cigarette...
not to mention, in the first interlude, he says: then please, my dark flame of vengeance would simply char my precious cigar. and as his flames are strong enough to burn sin itself, he would need a more gentle source of light but no less warm. it still burns hot, it still burns bright, but a different kind of flame... all too similar like a star... and so asks for your light and your strength in this moment where he alone is not enough. and so you respond, with that light in your hands to set that cigar alight
