"I wonder if it has the same... steampunk, clockwork look as First Aid and Vika. You know, on the inside," Chris muses, after hearing that explanation of building a seamoth from the available materials.

Lou is looking at the craft with wide, curious eyes. One wonders... if she understands what Bart is saying, maybe she's imagining exploring the ocean herself.

But Chris caught that calculating look on Calloway's face, and says, "Well, you said without the power source it wouldn't be able to work. What kind of power does it run on, Bart?"

(If it's something Calloway clearly hasn't heard about, then maybe Chris can haggle the price down. Bart doesn't seem well versed in how to get a good price in these situations, after all.)
