So... friendly terms would probably be an overstatement. He seems more frustrated than anything. Angry, sure, but not in... murderous, vengeful, plotting way or anything like that. It's still confusing though, partly because it's hard for him to imagine someone disliking Daniel this strongly. Then again, Seth is a little biased in that respect.

Seth's kind of unsure where to go from here - the conversation took a rather unexpected turn. He feels like he should probably inform Daniel of this development though, so he pulls out his phone. Rather than having to describe and explain, which would be highly impractical just at the moment, Seth decides to take a photo - he doesn't much care whether Rush would object to that at the moment. His level of worry and compassion for Rush has definitely taken a backseat with this new development.

He ends up accidentally taking a short video snippet instead, but that's probably just as well. And well-timed, too. He writes a short message, then sends it to Daniel, before pocketing the phone for a moment.

"So you know each other, then?" he asks, putting on an inappropriately casual voice.
