...Speaking of which, let me explain this first.

The coffee shop we found thankfully gave us their sales history,

And there were records of the old commander consistently buying from there.

And after figuring out the intervals of the commander's visits,

We took a look at every recent customer.

Card purchase history (Commander K)

Sales history

Cash payer's speculated route(?)

And there was only one person who payed with cash.

And by tracking the disguised commander through security footage...

We found that they were last captured near the wall.
