• Karn offered Kushina the Extremis Virus Serum to help her become stronger, and she agreed to receive it.

• Karn told Hatake Sakumo that becoming a Guardian Ninja could protect Kakashi and give Sakumo a future outside Konoha, and Sakumo said he would seriously consider it.
• After leaving the Hatake residence, Karn warned Rin Nohara that Sakumo might kill himself if the plan failed, then turned his attention to locating the Sky Ninja ruins.
• Kushina brought Tsunade and Nawaki to a training ground and used Nine-Tails Chakra Mode and her Adamantine Sealing Chains to narrowly defeat Nawaki.
• Kushina told Tsunade that Karn had given her an injection, and she demonstrated how her wounds healed as she explained that her chains could draw chakra from the Nine-Tails.
• Tsunade recognized the treatment as Extremis Virus Serum and privately asked Kushina whether she had received it in exchange for intimacy with Karn; Kushina denied it, though she blushed and wondered about the possibility.
