He was mentioned to have a new assignment dealing with the Phantomhives so it's possible. Also he's one of Yana's favorite, she's definably bringing him back.
I agree with vamp_grl_123. Ronald mentioned an assignment Grell had dealing with the Phantomhive household, so... there's just not much और to it than that lol. It's not unlikely.
I agree with emiliux123. He's there with Ronald Knoxx collecting souls from people eaten द्वारा zombies! Yay!!! Anyway आप will be looking आगे to the point when Grell sees Sebastian is there! Like Grell says, the purest form of प्यार is a death match! XD
