Platt, Halstead and others in “Unfinished Business”

Platt

Got word from headquarters. You're both up for mandatory firearms requalification. Get to the shooting range by Friday.

Halstead

Now, remind me, 'cause I'm drawing a blank here. Who was it that had the most shots in the black the last time we requalified?

Lindsay

I believe the operative words here are "last time".
