In the afternoon: The Butler, Laid to Rest

*3rd pov*

"Well, now that the professor has gone home... ...I shall see to luncheon–" Sebastian gets cut off. "Wait. I kept silent because it seemed like you purposely didn't want to bring it up in front of him, but... ...your haven't yet explained how Phelps's murder occurred." Ciel reminds him. "Ohh! Quite right!" Sebastian realized. "Actually, we had another visitor at the manor in addition to our invited guests." Sebastian announces. "!? What!?" Ciel is shocked. "He was right under our noses." (Y/n) said. "You knew as well!?" Ciel looks at (Y/n). "I actually found out when I saw the snake." (Y/n) tells him.

"As I was not expecting him, I showed him to these special accommodations here." Sebastian pulls out a big box under the table. "Wha—!? The killer is in here...!?" Ciel shouts. "Yes." Sebastian nods. "...Let me see what's inside." Ciel said. "Are you sure?" Sebastian asks him. "Don't put on airs. Open it!" Ciel orders. "Very well." Sebastian unlocks the box and opens it as two snakes jump at Ciel. "!!" Sebastian grabs the snakes as (Y/n) goes to the entrance of the greenhouse to get something.

Ciel falls down in surprise. "Wh–Wha–!?" Ciel is shocked. "They seem to bear you plenty of ill will, young master. Which is why I asked... 'are you sure?'" Sebastian helps Ciel up. Ciel turns to look and his eye widens. "!! Y-You're–! Snake!" Ciel is shocked again. "Mister Phelps's true murderer... The thirteenth person really did exist." Sebastian said.

<<<<<Rewind<<<<<

While Sebastian was making the food preparations in the kitchen. He heard the snake slithering in the vents of the manor. "It seems we have an uninvited guest." Sebastian checked his pocket watch.

*In Ciel's chambers*

"UAAAAH...!! HELP ME...!! Aah...! Oh! Ugh..." Phelps pleads as Sebastian just stands there and inspects the vent and leaves the room.

Sebastian heads to the greenhouse and a bunch of snakes fall on him as they bite and wrap around his body. "Well, well... It has been a while... ...Mister Snake." Sebastian looks at Snake. "I was born on Queimada Island, and my poison can kill any human in thirty seconds. So why aren't you dead yet? —Says Webster." Says Snake. "I am the butler of the Phantomhive Family. It goes without saying that I can withstand a poison of this potency." Sebastian's demon eyes glow in the dark.

>>>>>Present>>>>>

"Why are you here...!?" Ciel questions Snake. "The day after Black, Smile, and Kitty snuck into the tents and the other first-stringers, they all went missing. It must have been your doing! –Says Wilde. So I followed the scent of Smile's costume and went after him... —Says Oscar." Explains Snake.

*Flashback*

"Smile's smell is strong here. —Says Oscar." Snake looks at the townhouse. "Hey! What business do you have at this townhouse?" Soma and Agni stare at Snake. "Is there a small lad, a pretty lady all in blue, and a man all in black here? —Says Bronte." Questions Snake. "Small... Aah, you mean Lord Ciel, Miss (Y/n), and Mister Sebastian, yes? Begging your pardon, but may I ask your name–?" Agni gets cut off. "What's this? A guest of Ciel's, are you? Ciel's no longer here. He's gone back to his principal residence. But not to worry! I, Prince Soma, the viceroy who oversees this town house, shall deliver you to Ciel in the finest carriage available!!"

The carriage arrives and Snake gets in with a bag on his lap. "Say hello to Ciel and (Y/n) for me now!!" Soma said as the carriage leaves while Soma waves and Agni smiles.

Snake gets out and hides in the bushes. "There may be a party or something this evening. This is most convenient. —Says Keats." Snake stares at Arthur standing in front of the Phantomhive manor. "Let's bide our time somewhere until night falls. —Says Keats." Snake spots the greenhouse and heads inside. "It's so warm here. It's like paradise, don'cha think? —Saya Wilde." Snake eats the food Soma gave him.
