It has been a year since you (as Ratchet) got caught in the explosion setup by Captain Quark, who has joined Dr. Nefarious, that rendered you incontinent, and cost you both of your legs at the knee. The doctor told Clank your bladder muscles were completely destroyed, and there was no chance you'd recover while you were unconscious in the hospital.

You spent the first month hiding in the apartment you share with Clank, your little robot companion, trying to build yourself a new pair of legs. Two months, you received news that you'd been (presumed posthumously) promoted to Captain, replacing Quark. Three months in, you heard on the news that Quark was found and arrested. Six months in, you and Clank decided that you weren't going to care about what people think about your condition, and that you'd get back to the hero work you used to do. Today, you were out on a walk wearing nothing but your new legs, helmet, diaper, and the chest harness Clank clips onto as a backpack.

Clank: "Ratchet, are you enjoying our walk? This is the first time you've been out of the apartment since we got back from the hospital."
