"What other evidence do you have to offer?"
Grace asks kindly.
"We can conclude from the video that your robot was not the actual source of the explosion, but there is still the question of whether it caused it (though due to distance it is a little more unlikely)- and, forgive me- whether it was purposeful. You admit knowing the explosives were there, and you also admit to dropping something nearby that had an impact nearly simultaneous with the explosion- while not conclusive, this isn't exactly weighing in your favor, either."
