I just love it
Probably the best Merlin blooper ever. Not that we can be sure because there is another season or two (!!!) ahead of us, but that's definitely one of the best Colin/Bradley moments I've ever seen! Colin is his usual adorably cute self, and Bradley's "Oh, sorry, sorry, I'm sorry" just melts my heart. So much love!
Important note: the font I used for this gif is called "Bradley hand". How fitting is that! *g*
