While Cana is known as a boozehound to many, she actually has another bad habit…smoking. It’s something that relaxes her in her most stressful of times. She was the one who started smoking before Gray and gave him his first pack. Its one of the few things these best friends have in common.

So when interacting with Gray, she will most likely pick up her pack and zippo from her bag, or join him. Also, he’ll start smoking at her apartment when he’s stressed out as well.
