BLACK BUTLER ? HELP!!! (spoiler)?

Yea I'm really confused about that too lol. Sebastian ate Ciel's soul and all of a sudden they're having a party or something in the next episode (Don't remember that well). Maybe the last episode was a prologue to the second season. I haven't watched the second season yet and I didn't even think there was one because Ciel was dead until my friend told me.Maybe the second season will answer our question :)
