You Can Actually Pinpoint the Exact Moment the Series 5 Story Arc Begins

So I noticed several days ago that you can actually find the exact second that the TARDIS begins to malfunction and eventually explode. It's at the very end of The Waters of Mars, after the Doctor goes back into the TARDIS after seeing Ood Sigma. Right then, the cloister bell sounds, and it's never really explained why.

The cloister bell only sounds when something is seriously wrong with the TARDIS. I figure that at that exact moment, someone hacked into the TARDIS and installed a virus that caused some critical system malfunction to occur when it landed on June 26th 2010. The next time it landed on the date was in The Pandorica Opens, it took off on that date at the end of Flesh and Stone, but the virus must only be programmed for when it lands on that date, not when it takes off.

This would actually go against my theory about the Time Lords, which assumes that they hacked into the TARDIS during the Time War. It seems more likely that it was something the Silence did.

The Most Heartbreaking Part of the Time War

Okay, here's the thing about the Time War: the Doctor never acts alone. He always has a companion. Surely the Time War must have been no different. He must have had an accomplice in his conspiracy against the High Council. He must have had someone who was planning on helping him who would have gotten out alive with him.

Obviously, no such person survived the Time War with the Doctor. Even if he didn't have an accomplice helping him against the High Council, there must surely have been that one person who he was planning on saving. Be it his wife, his daughter, his brother or sister, Susan, Romana, whoever it was, he obviously couldn't save them. Something went wrong. Either they were attacked by the Daleks or captured by agents of the High Council. Whatever happened to them, the Doctor tried to save them, but couldn't. He had to continue his plan alone. He couldn't even save someone else instead. There wasn't enough time. He had to activate the moment and leave Gallifrey alone. I think that's the real reason the Doctor was so sad after the war, because he couldn't save anyone.
