What is a "concluding thought"?

THE NEXT MORNING, when I trudge into the training room, yawning, a large target stands at one end of the room, and next to the door is a table with knives strewn across it. Target practice again. At least it won’t hurt. Eric stands in the middle of the room, his posture so rigid it looks like someone replaced his spine with a metal rod. The sight of him makes me feel like all the air in the room is heavier, bearing down on me. At least when he was slouched against a wall, I could pretend he wasn’t here. Today I can’t pretend. “Tomorrow will be the last day of stage one,” Eric says. “You will resume fighting then. Today, you’ll be learning how to aim. Everyone pick up three knives.” His voice is deeper than usual. “And pay attention while Four demonstrates the correct technique for throwing them.” At first no one moves. “Now!” We scramble for daggers. They aren’t as heavy as guns, but they still feel strange in my hands, like I am not allowed to hold them. What does scramble mean here

Every thought I have condenses into that heartbeat, moving at the same rhythm. What does condense mean here

What is your favorite thing to do on a Saturday?

What does "tie up my phone with other people's business" mean?

How to distinguish between either means (both), and either means (one or other)? is there a difference?
