As I'll be using Codsworth a lot (perhaps exclusively if the rest of the companions don't particularly interest me) I hope that they'll give him a decent amount of development.

It would be nigh the best thing ever if he went from being the kind, docile robotic butler to an A.I-controlled weapon of mass destruction!

Imagine: "Sir, I think it might be prudent if we REDUCED THESE SAVAGES TO SMOKING PILES OF ASH. And then perhaps a spot of tea afterward!".

I just hope Codsworth has sarcastic remarks ala Raul.

“Yes sir, I shall await here for your return. Preferably not for 200 more years this time, yes?”

“Yes sir, I shall proceed to beat them to death with my metal arms rather than use my blowtorch. Very wise, good sir!!”

“Sir! Why do you wish to open my body to shove those-oh fine! Do get it over with, sir!”

I hope he stored 200 years quantity of jokes

Like Data from Star Trek?
