Skincare was something Argenti took Very seriously and he'd always put on a green face mask every morning and this became a routine you and Boothill had gotten used to.
One morning you had woken up and Boothill got up to get you, not realising Argenti's side of the bed was vacant since he was still half asleep. Boothill headed into your room and picked you up into his arms.
He then headed into the bathroom to brush your and his teeth, but then he was greeted to the sight of Argenti, doing his skincare which made you curious and you wanted to join in with being 'painted' green, and Argenti agreed (and he forced Boothill to have a mask on too.)
"Are ya kiddin' me? We look like darn aliens.." Boothill spoke as he looked in the mirror still holding you in his arms, all three of your faces decorated with the green sludge.
"Don't be silly dear, You'll stop complaining once your skin feels refreshed!" Argenti responded to Boothill while you pointed at the two of them and at the mirror, giggling at the fact you look like aliens.
