So-
In my alternate multiverse named Swap!ReCode (story that can be found on my book NorrustlerRoam's Alternates), Dream strongly believes that Cross is his older brother so he mostly stays with him.

And I did this small cute comic of they two

Drean also loves Cross' fluffy jacket.

And yeah, to differentiate him with any other Cross, this one uses mostly red themed or blue themed clothes in a monochromatic way.
