As well as Matt Elliot, I met another Doctor-alike, the lovely smiley Liam Dryden :D - http://liamdryden.tumblr.com/
Actually this was a rather embarrassing moment for me initially. My friend had already spoken to him at his booth, and as he passed us, this happened;
My friend: Look Lexi, David Tennant! ;)
Me: Oh yeah, he looks like him ^^
My friend: No, Liam Dryden!
Me: Yeah he looks like Liam doesn’t he?
My friend: No, no, it actually IS Liam Dryden.
Me: …. Oh! o_o
Despite my herp derp moment, he was very sweet and it was great to meet him :) Chattered away a little more at his booth as well, he was very friendly and it was lovely to chat to him :3
If you see this post Liam, thank you for putting up with the feathery lunatic!
