Spaceman Tetragrammaton

In my ongoing research into the Doctors Who, I get the feeling number four is the one you want to fuck with the least. It's actual cannon that he's insane -- he goes from zero to EVACUATE THIS SECTION I'M GOING TO DESTROY IT and then back again within the space of one scene. He's like the A-Team's H.M. Murdock with a time machine. Hell, he's like the entire A-Team with a time machine.

Four members in the A-Team, four as the eastern death number, four nucleobase types in DNA and RNA, four noble truths, Tetragrammaton the four-letter name of God OH SHIT IT'S ALL CONNECTED.
