What was Karl’s quote true meaning

Hello first post here,

anyways,

I was wondering if someone could elaborate a bit on the ending of the qoute of Karl (the lawyer 🙂 ) when entering the station in episode 7 in season 2, especially the ending:
“…to wit, this poor, mottled wretoh in front of me”.
I’m not a native speaker so i barely translated the words with all the internet’s help, let alone find the true meaning.

And i’ve searched if it is a quote from somewhere but it doesn’t show up so i guess it’s unique piece written just for the episode.

Thanks again 🙂
