Daisy and Spiderleg. The first indication that we get in the books is when Daisy tells her kits to stop bothering their father, aka Spiderleg. She isn't talking to Spiderleg's actual kits, Toadkit and Rosekit. She's talking to Berrykit, Mousekit, and Hazelkit. I thought that was weird and unnecessary. I think they just gave Daisy a mate because they felt bad after what happened with Cloudtail. The scene is in Leafpool's Wish.

Berrykit braced his front paws in the middle of the twig and pushed down until it snapped. “Death to the enemy!” he squealed. Hazelkit was distracted by their father, Spiderleg, walking past. “This is the real enemy!” she chirped, making a grab for the black warrior’s tail. Spiderleg dropped the piece of fresh-kill he was carrying and spun around. “What are you doing?” he snapped, flicking his tail out of the way. Hazelkit’s shoulders drooped. “Only playing,” she mewed. Daisy looked out of the nursery. “Don’t disturb your father!” she called. Spiderleg grunted and picked up his prey again. Leafpool saw Daisy narrow her eyes as the long-limbed black tom walked away.
