From the PM:

"The knife landed 100%. They both said “yeah, the knife whispered to her and lead to the location.” Done and done.

Canons also made sense, neither felt like they really missed something. The explanation that hitting the cannons takes out the ships was sufficient for them. Gavin said he was actually happy it wasn’t over-explained or focused on because, in his words, “the previous two films leaned too heavily on that anyway.” Once I told them why the cannons were what they were in the original cut, they both said that the size and scope of the fleet was sufficiently intimidating."
