[It's breaking his heart and he can't pull Peter close enough, holding him as tightly as he can manage.] Think about it: you've already saved more people than I'm sure, any of your paramedic counterparts; than most people could ever hope to in their entire lives; than I have in 400 years. Granted, I wasn't trying too hard. [He brushes his lips over Peter's forehead, trying to keep his speech light.] There will always be people you can't save, but for that person there will be ten more you can. You can't give up, Peter, it's not in your nature.
