Do Two Half Measures Equal a Full Measure?
Cause that's what Mike should have done with Werner and Kai after their R&R excursion: A half measure for Werner for talking about stuff he shouldn't have to complete strangers, and another half measure for Kai for almost getting arrested.
If he had, maybe [spoiler]Werner would have thought twice about escaping and getting himself killed and maybe the German crew could have finished the job.[/spoiler]
