Requiem of the soul

Bilbo follows Thorin on his quest to reclaim his home however the reason he gives is far from the truth. Will the Dwarfs notice anything or will it need to be spelled out for them. Bilbo is no ordinary hobbit. Hes lived before, died and was given another safer body. His horrid past gives him the strength to fight but why when he does, does his body look... odd. mentions murder.
