Question from a non native speaker:
The brute ability “when you investigate a mysterious object by breaking it, ask a follow up question” means:
1) ask one more question from the list
or
2) Once, you can ask a question that clarifies some details of what you have been told, like
Brute: “What memories does this candle hold”
GK: “You see a servant keeping it on the bride, lettin the wax drip in her mouth”
Brute: “Was he actin on his own? or on Bluebeard’s orders?”
The example in the book suggests it’s (1) ask one more question from the list.
