At least Shoto's declaration and promise makes him smile a little bit. "Salmon." That he can agree to. He wouldn't run off and leave Shoto behind, they could work together. If they died together then...well he will make sure that doesn't happen. In the eleventh hour, he would save Shoto's life in a heartbeat.
