"Wait. Don't--just don't talk for... give me one minute. Time it if you have to."

It's not that Dirk needs a minute to put the pieces together. It's very much the opposite--he is hit with so many connecting pieces that the kickback from all those parts suddenly jerking into place and beginning their movement that it's actually difficult for him to steer the resulting machinery he's been put at the controls to.

Some of that difficulty is actually that he's trying, in the moment, not to be angry at Hythlodaeus.
