Definitely has a scar now.
Just to copy from a comment I made in another thread, he's definitely gained at least one scar from his accident it seems, no biggie really -
Actually I'd say it looks like he's got quite a big scar above his left eye, about an inch above his eyebrow from the middle of his forehead right around to his hairline. It's been well stitched (as it obviously would be, considering) but definitely something there.

Make-up will easily cover that for TV/Film work as it's been well cleaned up and flattened out, hasn't affected the shape of his face or eye - pretty light so it'll fade even more with time too.
