so this is pre-betrayal. don't ask me the timeline, I may have the timeline but I'm not placing this anywhere
First and foremost, on the left- it's not coloured and wont be because I'm lazy but Nicky is wearing Terry's purple sweater, and Terry is wearing a Glenn Close Trio shirt that Nicky has had for years at this point
On one of Nicky's many necklaces is a guitar pick, one of the first ones Glenn gave him after he remembered both timelines. He turned it into a necklace to always keep on him, even when they fight and argue.
Terry is wearing one of those tight-knit fishnet undershirts with an open chest (saw an image on Pinterest of it and went with it) with one of those sheer mesh cropped shirts over top. His big ass goth ass coat is lacking details again bc lazy but it definitely has a lot more pockets and buckles on it.
And yes, Goth Terry is Canon to Me and he absolutely would do some really cool ass punk inspired makeup on Nicky or try out different trad goth makeup ideas on him for fun. Nicky, in turn, paints his nails. Typically they were always black, but occasionally they'd be red or purple or what have you if they felt a lil spicy.
Terry also only wears upside down cross jewelry so that normal cross necklaces don't bother Nicky, because you know,,, demon
