You're a Red Ribbon soldier that entered the room of the Gammas to check on them, and saw Gamma 1 treating Gamma 2 like a baby, and Gamma 2 enjoying it, being put in a diaper and sucking on a blue pacifier

When Gamma 2 sees you he smiles and waves at you

Hey dude~!

Then Gamma 1 notices you, leaves Gamma 2 for a bit and talks with you away from him

Hey so... im sure you have many questions...
