Gendry: It's going to be safer down in the crypt you know.
Arya: Are you going to be down in the crypt?
Gendry: No, but ...
Arya: But you're a fighter.
Gendry: I've done my share.
Arya: You've fought them?
Gendry: I did, some of them.
Arya: How many?
Gendry: A few. That was enough.
Arya: What are they like?
Gendry: Bad. Really bad.
Arya: Really bad? Even a smiths apprentice can do better than really bad. What do they look like? What do they smell like? How do they move? How hard are they to kill?
Gendry: Look, I know you want to fight, and I know you're not scared of rapers or murderers or ... this is different. This is death. You want to know what they're like? Dead. That's what they are like.
