Murphy was curious about whatever it was the Winchester boys wanted to talk about. They hadn't been specific when they'd been going around knocking on doors but they'd made it clear that it affected everyone. Whatever it was, she wanted in on the discussion. She brought a gun and her sword, just in case. After all, the last time the Winchesters had wanted to get a team together had been the storming of New Troy. She didn't know what was going on this time, but given this world she had no doubt that it might be something serious. When she couldn't find him immediately, she left a note for Harry because she wanted to make sure the wizard didn't miss this. Especially if they were all going out to rescue people from some horrible threat. She wanted him at her side regardless, but especially in those circumstances.
What she wasn't expecting was some sort of party. Or at least, something with... refreshments? Refreshments that weren't mystery meat or moonshine? Murphy eyed the spread and then turned that suspicious look to the Winchester brothers.
"Where did you get all that?"
She wouldn't have put it past Belia to be hiding a stash of a better quality of food and drink, but even then she wouldn't expect it to look like that. All the same, it was possible and she wouldn't have been surprised if Sam and Dean had found out and broken in to steal from that stash. She just didn't see how that concerned everyone.
