Ha! In all actuality, once I realized that I was going to be there for a while before I would get tired, and because I dropped some of my food because it would just be overnight, I did grab a book to read. However, because I failed to get a fire going and had to hunker down in my bag, I couldn't comfortably read.

And in regards to warmth in the tent, I had a huge 3 person tent, so that was a lot of space for the cold to win out over any heat my body produced! I'm definitely going to get a bivy style shelter (like a hoop supported structure) to camp with in the future. I can leave the netting full open in the summer and close it up in the winter to preserve heat.

EDIT: Oh and in regards to the candle lantern, I've never tried it, but that does put out some serious heat at the top. I have one and have used it, especially when we moved and the electricity wasn't sorted. I'd be kind of worried about melting my tent, to be honest. Though I've never tried, so I could be wrong. Wouldn't be the first or the last time.
