Zim stopped before they reached the room again, and sat down on a seat in defeat. He so wanted to tell Yin how he felt, but knew that he just couldn't do it. He didn't want to be laughed at or rejected. But most of all, he didn't want to lose her friendship. As he thought about it, he realised that it was more than that - he didn't want anything to change. He loved their play-fights and fun arguments. His heart beat faster when she complimented one of his plans or thanked him, but it only meant so much because she usually didn't praise him at all. And he liked it that way. He enjoyed the banter, and he'd miss it terribly. Of course he wanted to tell her how he felt, but not quite yet. Perhaps after the mission, or Operation Impending Doom II altogether. He didn't want to rush it, not at all. Plus... what if she didn't even want the same thing? It made his heart ache, but he knew that there was a huge chance that she wouldn't even want to be with him. She might even love someone else!
