"A Touching Reunion! Momonosuke and Kin'emon" is the 622nd episode of the One Piece anime.

Short Summary
The Straw Hat Pirates and the Marines are about to enjoy a large dish prepared by Sanji, though the Marines are still adamant in keeping themselves from being friends with pirates. While the stove is being constructed, many events occurred; Kin'emon was actually alive the whole time, Law removed the drug from the children, Momonosuke's human form is revealed, Nami complied to Tashigi's plea to let her take care of the children, Mocha has recovered fully from the drug overdose and the poison gas is revealed to be lethal after a full day's effect.

While the group celebrates their victory, Smoker talks with Law about him manipulating Luffy, but Law says that its the other way around. Previously, during their encounter in the mountains, Law revealed his goal to defeat Kaido with Luffy's help, but Luffy expressed his desire to defeat all four of the Yonko.
