Care is one of the many forms of Inner Jack and one of the two positive personalities.
Care appeared to Samurai Jack as a reflection from his post-traumatic stress disorder look. He obviously cares about Jack's well being and asked him what he was going to do, he later disappeared after Jack and Ashi were getting ready to eat dinner.
- "Be careful."
- What are you going to do?"
- Care is the second Positive form of Inner Jack and the First in Season 5.
- Care's reflection in the glass was possibly Jack looking back at the time he lost his sword.
