Now that we think about it, Harry Potter‘s Neville Longbottom would have made a great addition to the Stranger Things crew of lovable misfits. In an Instagram posted by Longbottom’s portrayer Matthew Lewis on Sunday, fantasy worlds collided as he hung out with Millie Bobby Brown, a.k.a. Eleven from Stranger Things, and jokingly revealed the inspiration behind his “XI” tattoo.
In the cute pic, Lewis shows off the Roman numeral 11 tattoo on his forearm while Brown points at it sporting a funny face. “A lot of people ask what my tattoo means. Now you know,” Lewis captioned the photo, implying that Brown’s character was the reason for the ink.
As it turns out, Lewis has actually had the tattoo for several years now (sure, it was way before Stranger Things premiered, but nothing a Time Turner can’t fix, right?) and said at Dragon Con in 2008 that its real meaning comes from his soccer squad number. “It was on my mind for ages what to get, so I said, why not get that because it’s always going to be my squad number, it’s never going to change,” he said.
