Summary: Catherine takes Lizzie and Ciel to Undertaker's shop for protection while Sebastian is sent to retrieve some information as well as kill a dangerous opponent. Undertaker somehow convinces Ciel to have himself fitted for a coffin and seeing him agree, Lizzie joins in too. Catherine sings an interesting song. Inspired by Florence + The Machine's My Boy Builds Coffins.

'Why must we stay here?' Ciel sighed, complaining where he was standing opposite Catherine, Lizzie on his arm.

Catherine was sitting on a black red-lined coffin, stroking the sides almost lovingly. 'Because brother has gone on your orders and I'm to care for you both here. The home of a shinigami… wouldn't you agree it is very well fortified?' She questioned, completely at ease.

Undertaker emerged from the backroom after covering the corpses, taking the hand of his lover with a giggle. 'I'm honoured, my dear. It's only too bad that the earl and his lady are not enjoying themselves.' He said smoothly.

'Yes, he is not as fond of your fine craftsmanship as I am.' Catherine spoke with a slight tone to it. One that Ciel did not miss. He raised one fine brow.

'Are you implying that I do not appreciate fine art?' He demanded, his blue eye sharp. Lizzie watched with rapt interest in her green eyes.

'Not at all, merely that I do.' She continued slyly, lowering herself into the coffin that was made for her. It was sinfully comfortable in there and she and Undertaker usually spent their time in it. Or in his…

'And that I don't.' Ciel fumed. Lizzie struggled not to gush how adorable Ciel looked when he was irritated.

Catherine opened her mouth to say something but Undertaker kissed her hand to stop her. Running his black nails on her hand chidingly, he smiled with amusement. 'Now, now, my dear why don't we let the young earl prove it?' He suggested but only Catherine heard the layers in his voice.

'Excuse me?' Ciel asked, raising his brow once again, this time in an incredulous fashion.

'Well, earl? Will you allow me to build a coffin for you to prove your appreciation for my art?' He worded smartly, holding out his hand. Ciel didn't take it but he stepped away from Lizzie proudly.

'Very well.'

Undertaker picked him up and plopped him onto what he had thought was a table but now the boy realized that it was the wood for the bottom of the coffin. 'Now then, lie still, earl.' Undertaker said gleefully, pleased at finally having the opportunity to make a coffin for the young earl who sold his soul.

Lizzie looked at Ciel, lying for his coffin to be made. She would hate to see him in a coffin. He wasn't meant to be in that… no matter how beautiful. He's meant to be with her. He's not going to die! Catherine sat in her coffin, watching her lady with interested eyes. Lizzie put on a smile, her resolve unbreakable. She would join him in whatever he did. If deathless people were having coffins built than so should she. She pulled lightly on one of the hat ribbons Undertaker wore and he turned to her with a happy smile. She returned it.

'Will you be so kind as to make one for me as well?' she asked in her most polite and adorable way. Ciel turned to look at her, his blue eye wide with surprise.

'Lizzie…'

'Why, of course! What a loyal little fiancée you are!' Undertaker gushed picking her up and laying her beside Ciel. He took her hand and she blushed with pleasure at the compliment and the contact. Catherine giggled to see Undertaker so absolutely delighted now. He set about making measurements on the wood immediately. Catherine folded her arms and leaned her head on them, opening her mouth to spill forth a song.

Undertaker grinned in a silly manner upon hearing the first line. Even Ciel looked amused and Lizzie was trying to hold back giggles. Undertaker let out a low chuckle though but Catherine didn't stop singing about her boy that builds coffins for everybody. She did however give him a flash of her pointed canines when he turned to glimpse her, lounging in the coffin he made for her, her black hair cascading to frame her pale face. Pale as a corpse…

'An interesting song, sister.' Sebastian quipped wryly. Catherine shot him a look.

'As interesting as your lullaby?' She jibed innocently. He purposefully ignored her as he strode to Ciel and Lizzie.

'Shall we depart, my lord?' He asked, looking with amused red eyes at the master who was having his coffin made… alongside his soon to be immortal fiancée.

To his surprise, he was met with Ciel's serene smile, comforted by Lizzie's presence. 'No, let the Undertaker finish his work.'
