This takes place on Noveria. And I was too lazy to fact-check so if I got anything wrong about how to do the puzzle thing, blame Trick. He has no idea what he's doing.
Trick stared at the mainframe computer. He had to transfer blocks to a certain column, but he had to do it a certain way. Damn, he couldn't remember what he was supposed to do. He was never good at puzzles like this. He made a promise to himself to download something to his omni-tool to help him practice things like this. You never knew what you could come across, and next time he was going to be a little more prepared.
He started randomly switching blocks around, hoping he'd get lucky.
"Commander, are you sure you know what you're doing?" Kaidan asked from behind him.
"Not a fucking clue," Trick replied.
"Let me try," Kaidan said.
Trick moved and let Kaidan take over.
In less than a minute Kaidan had the thing solved.
"Good job, Alenko," Trick said. To hell with downloading something to help with those things, he'd just take Kaidan everywhere. He really liked that plan.
