I don't remember which part it's in, and he doesn't delve into the details of what it is like how I wrote him explaining it, but it's the most in-depth explanation I've found of him ever saying anything. He also ties it in with Vegas, which is where I got some of the facts for the story :)
Hello! I know that it's not normally the Alex-type thing to do - being rude in an interview - but looking at the situation from a completely outside perspective, most of what he said had double meanings, and the most horrid parts were really just his expressions and tone of voice. You like, whatever it is, the person who is asking you all these questions is someone who you haven't seen since the night they confessed that they ruined everything you two had worked for. And although we all see Alex as an amazing guy, he still is human. Haha that was long.
Anyways, yes there is in fact a video of him talking about Remembering Sunday. I actually have it on my iPod, so as soon as I find it, I'll link you to it :)
