"Don't hold back! Give it all you have! Show me a nice strong warp! Beat the f-fancy boys!"
The sounds of detonations.
"You there, Bellarmine! Try harder!"
"But I'm doing my best, ma'am!"
"Not you, Seanne, your brother over there! You do that in a real fight, Reiley, your candy ass gets handed over! Understood?"
"Yes, ma'am!"
"Now, all of you! A barrier for thirty seconds, then on my mark, shock them with all you have!"
Jack's countdown on the background of strained breathing, and then a concentrated biotic blast causes the loudspeakers to clunk. The clunk is followed by loud cheering. "We destroyed them! Psychotic biotics! Yeah!"
"You beat them alright but you panted like krogans in- uh – ". Cough. "And, Prangley, that barrier was weak! That last round almost got through, and these are just puffy soft balls! You wouldn't be such a cutie any more if some real stuff smacked you!"
Several girls giggle, and Kahlee feels her corners turn up. Poor Jason has probably turned all red to match his hair, and his "Yes, ma'am" lacks the usual enthusiasm.
Turning down the volume, Kahlee sits back to watch the students forming pairs for the next exercise while Jack, her eyes shining, goes from pair to pair to administer praise and tongue lashing in equal measure.
They are eating from her hand.
Despite all her initial misgivings, Kahlee has to admit that the risky choice of the new biotic teacher has turned out to be exactly what the students needed to become fully committed to the training.
That's what full commitment usually inspires, after all.
