I am definitely not a fan of Mark but I do think Christopher has the measure of him. The waking up video in the garden with Chris and Christopher was quite funny. I also think Mark is massively insecure about showing any affection or admitting his fondness for Christopher. I have to admit to being somewhat like it myself when I was in my teens and early twenties. I would never admit to fancying anyone and if friends said anything even slightly off about the person then I immediately thought I was wrong for liking the person I fancied.
