since Fritz is rp Katte, not himself, adressing Goltz as Fritz, him saying "I live in you" certainly is more poignant.

Oh, damn. Yes, that's way more powerful. Wow, these subtitles are just not doing justice. (Although I did like the poesy--the impact is harder with "live," given all the context. I mean, that's just a different way of phrasing the last line of "Pulvis et Umbra.")

he's using "Du" not "Sie"

Oh, interesting, so another fictional example of Fritz/Katte Du-ing each other.
