I have a feeling I know what it's all hinting towards but I cannot honestly say I feel conclusive enough about it to write a huge explanation here..

The one thing I will say though is that the 'tea kettles' are not exclusive to Jeffries, there's a scene somewhere late in Season 3 where you can see rows and rows of these things for miles, seemingly endless - I think that should give you a big hint as to what it all means.
