If you asked Skarr, people got too bent out of shape over the small stuff. Yes, he wasn't heartless. He would have rather the hatchling humans have lived. He felt the ping of regret about as much as anyone. The difference was, he didn't dwell on it. He'd seen exploding transport ships, ships that he could have saved if he was just the smallest bit faster. He saw the bodies filter out of the ruptured hull, doomed to float into the recesses of space. 

If you let that stuff get to you, you were going to have a bad time. It was good to know the mission was a relative success. Hopefully he'd get his first cut soon. He'd conserve his money, but he didn't know how much longer he could pay for his meals with the banks on this planet. Plus he was eyeing the latest series of Claymore guns. 

He decided to grab a small meal, merely 5 pounds of what the humans called pork. Earth had quite a lot of odd, albeit tasty livestock. Only dropping two atomic bombs on their soil left alive a lot of critters. Odd the only beasts close to Thresher maw in size were the Elcor looking Elephants, and the marine life called 'Whales.' You'd think a lot of the creatures on this world would be huge. 

He filled one of his multiple stomachs with the pork, but found he had little interest in exploring this bastion of civilization. He'd probably break more than he'd care to pay for. So he made his way to the platform, formerly 'New Scotland Yard.' Salissa was the only one there he saw. If he was a younger Krogan, he'd make a joke about her being only the third human to 'mount' him, but as it were he just found he respected her fighting prowess. She seemed unnecessarily tough for a slim human female. 

"Good job out there," he told her.
