Sesshomaru liked Kouga, though in a rather odd way. Kouga reminded him of Inuyasha and he wondered if he'd finally found someone to look after again. He was younger than Sesshomaru was and obviously still had a bit to learn but was willing to be responsible for his actions. And that made Sesshomaru think, would this be what Inuyasha would have been like if he'd been here?
"You okay man?" Kouga's voice interrupted his thoughts. "You just kind of zoned out for a second." Sesshomaru wasn't sure of what to say and after a few minutes finally graced Kouga with a simple response.
"You remind me of someone." And as he heard Kagome gasp he knew that she'd figured it out.
