I am currently drafting a Regulus Black book because he needs love and the headcanon popped into my head that after living with Sirius (especially during the time Sirius was rebelling and drifting while Regulus didn't want to loose his brother) Regulus knows a silent charm to use his thumb as a lighter So Sirius would just have it in his mouth trying to work the damned Muggle thing and Regulus would walk over and effortlessly light it for him.
