Dr. Who/Horrible

So my friend, Tenkan, has been trying to get me to watch Dr. Who for a little while now. It was on last night, and my mom (who was watching with me) is a fan, so I watched it. After some research online I conducted today, I found the episode was called "Love and Monsters." The ending was pretty creepy, yeah. If you've seen it, you know what I'm talking about.

But the thing is... the main character of that episode (not one of the recurring characters like the Doctor or Rose or something, I guess), Elton, looked remarkably like Billy, of Dr. Horrible fame.

I kid you not.

So, for more of my reference than for any readers' (yeah, plural... I'm hoping), I'm going to post some picture links cross-examining them:

Spoilers if you care about them:
So, video blog for Elton and Billy.
By the time Elton got to the laundromat, I was pretty much squeeing at the coincidence.
Not to mention when he got his girlfriend, you know, dead in the second-to-last set. SAME LOOK on his face. (Fortunately he got her back... in a really creepy way. But I suppose that's normal for Dr. Who?)

<3 Billy lookalike

(Also--fairly obviously, I didn't make the screencaps. Just to get that out there)
