[Small lil spoiler warning 4 the Ash and Marcel lore!]
Something something Ashril and Marcel r a mix of prison duo & devious lads/wet birds.
Centross helped Icarus out of their doubts and comforts them when they need it most.
Marcel did that 4 Ash and promised to do that more for them in the future.
Ven did similar for Icarus as well as sharing work and making sure each other was okay everytime they saw eachother and after whatever they did that day.
Marcel and Ash do the same 4 eachother.
Something something...
