Considering they're both British, it really was only a matter of time before television's latest cult hero came face to face with Harry Potter fan favourite Neville Longbottom. 

It's a small industry after all. We're not sure what the exact circumstances of the meeting were but it sure as hell left us with a lot of unanswered questions.

Particularly with regards to Matthew Lewis' roman numerals tattoo.

 

A lot of people ask what my tattoo means. Now you know. @milliebobby_brown #XI #Eleven

Do we just chalk the tattoo down to pure coincidence? Or can we take the more logical approach and present this as proof that Eleven is actually a witch?

Either way, the campaign to get Lewis to cameo in season 2 starts here.
