'Carrot juice, carrot juice, carrot juice' - does it work?

So, Six's last lines as he leaves behind the Trial. With the context of what was going on behind the scenes, it does have a sad, slightly pathetic sting to it. However, like with the abrupt 'I'll take you to--' in Revelation, I sort of like how inocuous and small-scale it is - only in Who could you go from sci-fi conspiracy thriller to having your lead worry about having to exercise and dreading the prospect of veggie juice as he flies off into the cosmos. It's so wonderfully English in its quaintness that it provides a strange yet nice button on Trial.

How's anyone else feel about the line?
