Yeah.
Random thought: Haley's using a really low anchor point for an archer. Yes, I did just complain about anatomy in a stick figure comic. You may all point and laugh now.
Fuse the "competence = mechanical strength" error with reading just the title of Trap Sense, and you have it.
I didn't say the argument was correct, just that it made sense.
I'd like to revise some earlier remarks I made: although Tarquin has been walking down narrow trap-filled hallways for some time now, the remarks bringing the LG's discussion back to traps, and particularly traps that aren't merely mechanical ("It takes a booby trap to find one"), could serve as a unique trigger for T's thought processes. Add in the suitable location, and Tarquin's timely realization is, contra my previous objection, quite natural.
