Just a regular Grimmjow X Ulquiorra thing. They are at Las Noches in Hueco Mundo, Aizen rules over them. Ulquiorra is Fourth espada and Grimmjow is Sixth.

Ulquiorra Cifer, Cuatro (4) espada : http://bleach.wikia.com/wiki/Ulquiorra_Cifer (played by me)
Grimmjow Jaegerjaquez, Sexta (6) Espada: http://bleach.wikia.com/wiki/Grimmjow_Jaegerjaquez (Played by you)
So basically, Grimmjow is tired of Ulquiorra showing no emotion and keeps trying to make him. Eventually... Grimmjow does something that makes them both realize something.
