Adam didn't know Alastor, but he knew Angel Dust?

So, If Adam didn't know Alastor, how could he know Angel? Short theory:In his room with lights off, Adam watches Angel Dust. He even simps for him! So, when he got killed, he will respawn in hell, and will follow Angel any where. All he could think of is Angel's big thing. Then, Val founds about this and trick Adam to make a contract with him. Val would love to have Adam so much, that he would left Angel in the background. Everyone will have a happy ending:

Val will have a new and interesting soul(and d*** preferable 24/7)

Angel will send more time at the hotel

Adam will be the d***master he always wished to be

Now i ask you, how does this theory feels for you? Do you have other thoughts on why Adam didn't know Alastor, but knew Angel Dust? (I didn't have proper photos, so i put some which i already had)
