I have a funny headcanon about Snape's role within the DE circle.
Like, yeah he became a spy because he was really good at being stealthy and unremarkable but before that of course Lucius was talking to everybody about his potions skills. The guy was a malnourished greasy 17yo but also a fricking genius.
And ofc he made poisons or other stuff but my hc is that one of the thing he made consistently for the Dark Lordβ’ was... handcream.
Because of course old Tomy liked to look good and smell good and he had a handcream he used for years then it was discontinued and he was so pissed off (and everyone heard about it) and Severus made him a new one - even better - with the same fragrance and this is how he got noticed by the DL himself.
And when the Dark Lordβ’ came back... he made it again (and had to adjust the formula because his skin was different now) and it just cracks me up to imagine Dumbledore with a grave voice being like "So, Severus my boy, any news from your last meeting with Voldemort?" and Severus to be like "Lavender is now offensive to him, I need to find an adequate replacement." and Dumbledore being like "...what."
