>Garp has been shown to supress reports about Rayleigh
>Garp insisted on being in charge of all Dragon related matters, it works because no one knew they were related until Marineford
>Regularly gives Dragon intel about the marines and the WG and keeps them from hindering the Revolutionaries
>When Dragon told him everything was ready to lay siege to Marijois, Garp went on a suicide mission to Hachinsou because his work was done and he was sick of his life
