Spider?

                                    

                                          
A/n: No actual spiders, got it?

Your POV
"You guys are finally back!" Lance exclaimed. 
Everyone walked down to the pod hangers. Allura and Coran returned from their trip to the Balmera. 
"Yes, there was lots to do. How was it here, in the Castle?" Coran played with his moustache .
"Everyone's back to normal, as you can see. Nothing too bad." Keith replied reluctantly.
"We faced a Galra fleet a few hours-er-vargas after you left. And Lance claimed that he saw a wormhole." you quickly said. Allura looked affronted.
"Another wormhole? That couldn't have been me, and the Castle wouldn't activate one in peace." 
"Let's go to the bridge." Shiro left. Pidge was typing furiously on her wrist device.
"The pod is damaged. I can fix it." Pidge said after a scan. "Yup, one of the metal bars inside broke down and the engine overheated."
"Sure. We'll fill you in later then." Coran skipped away. 
"I'll help." Hunk bent down and grabbed a blowtorch out of nowhere.
You nodded to Allura and took the short way to the bridge, passing the kitchen.
You turned your head sharply when you heard a crash in the kitchen. You activated your bayard quickly and raised your katana.
You glanced at a rolling can of scaultrite powder and a toppled chair. More rustling in the cabinet to the corner, and you dashed to it and opened the cabinet door.
There was nothing in the cabinet except for a rattling spoon. It spun on the tip before falling and staying still.
You stared at the spoon and slammed the cabinet door. The kitchen had been searched by someone right before you passed. It couldn't be Pidge or Hunk or Lance or Keith or Shiro because they were doing other stuff. You scanned the room, found nothing, then made your way to the bridge.
"The kitchen was disturbed on my way here. Someone or something's in the Castle." you reported as soon as you walked in.
"I'll take a quick scan." Allura turned away to the bridge Castle control things. The other paladins did a what-happened-there gesture. You replied with a maybe-later-now-look movement.
You glanced at the huge screen at the front of the bridge. It displayed everyone in the Castle as colored dots. Red, black, blue, orange, white, and pink dots were at the front, which was the bridge. Yellow and green dots were in the Altean pod hanger, while a strange grey spot was moving around in the kitchen.
"Y/n's right, something's in the kitchen." Lance pointed at the kitchen on the scanned map.
"Maybe something Galra. If it was one of our belongings, the Castle wouldn't put it on the map." Coran supplied.
"We'll check it out." Keith grabbed Shiro's arm and dragged him out of the Castle with his sword in his left hand.
You watched the sliding door close and looked at Allura.
"Keith, Shiro, get rid of it quickly. It could also be a Galra tracker that was placed in the Castle somehow." Allura reasoned. 
"Got it." Keith said. A loud, sonorous crash was heard somewhere in the Castle. A yell, then more crashes, and then footsteps. Keith reappeared at the door, his bayard gone.
"Are you alright?" Lance cocked his head. Keith groaned and leaned against the wall, shaken.
"Keith, it's gone." Shiro came running quickly with the red bayard.
