"At least you understood the concept of commerce. That was more than I did." Because everything he needed? Just showed up. Extra weaponry? Jump packs? Food? He had to worry about none of it back home. Simply killing as many of the enemy as he could before the Emperor called him home.

"Things are distressingly not difficult to kill here." Almost...boring. "I could lend you a weapon, at least." She might struggle with his sword, but he did have a combat knife.
