How?

The first thing Hal did when Tanya said those words, was to turn around and look at Ehrlich and sure enough, he was grinning.

Hal shook his head and sighed, 

"What do you want me to say? Apologize for killing him? Because I won't" he said.

Tanya shook her head, 

"No I don't want you to apologize for killing him" she said and the grin was immediately wiped off Ehrlich's face,

"Y-y-you don't?" He asked in disbelief while Hal allowed a smile to play on his lips.

Tanya shook her head, 

"No, I don't. Would I have preferred the supplier be captured alive and well enough to tell us how he made it into the empire? Absolutely, but I also understand how things don't always go according to plan.

In fact, I believe you deserve more commendation" she said to Hal.

"You do?" Ehrlich asked and once again, there was incredulity coloring his words.
