Wordlessly, Lord El-Melloi II reaches into his coat pocket, and what he pulls out is a cigar case that's as fine as his title suggests such a thing should be. The cigar he takes out is one of the ones laced with his own mystic code. He hasn't had need for them lately, and so to give Roman one is a good idea.

"Take a lighter with you. The code won't function otherwise."

Easy solution. Even if he'll get scolded for encouraging smoking.
