(Faces the Runner) I'm concerned about your naming convention. The labels you choose strike me as entirely arbitrary, and worse, uninformative.
I worry that it will reflect poorly on us upon our return, if each tunnel is assigned nothing but a letter. By way of example, the letter "D" is a fantastically dull appellation for this tunnel, especially when compared with the numerous other possibilities.
(Thinking to herself: Does it even matter that much?)
(Begins to walk away) ...
Oh, alright. If you really want to, you can name a tunnel or two.
(Continues to walk and jump away)
(Off-screen) Hmm... what would be a good name? It has to appeal to the right sort of people... And it certainly ought to reflect the bright colors and patterns in this tunnel.
