Honestly, considering the usual amounts of violence the train can withstand, it's true that an explosion is probably nothing to it.

But it's something Inigo hasn't tried yet, and that means he has to cling to this right now. He has to make sure to at least have tried everything, no matter how ridiculous.

"Maybe it might make the train finally notice us," he says - no, desperately hopes.

Because he isn't too sure what else is going to make it notice them.

"I think we just have to cause enough of a ruscus here on the platform that it simply can't ignore us anymore."
