[ In this conversation, Light lacks a lot of key elements. Mello may know him, but the reverse isn't true and thus, he can't know just how brilliant a mind his future enemy holds.

It's healed skin, not an injury so it's not something I've studied. With the size and probably depth of the scar, it'd take a very good healer, if it is possible.

[ Ironically, Kira has specialized in healing. It wasn't necessarily intentional. Both of his preferred magic specifications taught healing and since he does want to keep himself alive, Light's been willing to put in a lot of extra work as well. ]

Burn injuries are a lot more severe than most, and the damage goes deeper.
