Tintin: We failed.
Captain Haddock: Failed. There are plenty of others willing to call you a failure. A fool. A loser. A hopeless souse. Don't you ever say it of yourself. You send out the wrong signal, that is what people pick up. Don't you understand? You care about something, you fight for it. You hit a wall, you push through it. There's something you need to know about failure, Tintin. You can never let it defeat you.
Tintin: We've got bad news. We've only got one bullet.
Captain Haddock: What's the good news?
Tintin: We've got ONE bullet.
Captain Haddock: So you thought you'd sneak in an' catch me with me trousers down, eh?
Tintin: Would rather you kept your trousers on if it's all the same to you!
Tintin: What have you done?
Captain Haddock: I lit a wee fire...
Tintin: IN A BOAT?
Chosen answer: He must have thought that Snowy had found the magnifying glass and was playing with it. Like most dogs would do with a toy.
