Back at the Emiya residence

Rin's managed to finally get Berserker from clinging onto you. With breathing room back on your side, you sit next to Caster in the living room with Rin and Berserker sitting across the table from you.

"I can't believe you summoned Caster. You're not even a Magus. The Caster class needs more prana than any other class! How in the world are you going to sustain your servant? You don't even have any magic circuits!" Rin scolds.

"I will not allow you to talk about my precious husband like that." Caster interjects. Her tail swishes aggrivatedly.

"Caster, it's okay. She's right you know. The only thing I am capable of is reinforcement magic." You reply, taking Caster's hand in yours and calming her agitation.

Rin's eyes narrow as she scolds you further. "No self-respecting mage would ever even consider specializing in such a worthless ability. But humor me. Show me."

You sigh. You hate Kiritsugu never showed you magic. It **** you to practice in secret and come up with.. this.

"Well what are you waiting for, we don't have all day!" Rin chides. Your body visably tenses. You suddenly feel Caster's hands on your shoulders. Her soft tail comforts you by wrapping itself around your waist. She rests her soft, slightly furry face against your own. "You can do it. I believe in you." Caster says. You reach out and grab a pencil that is laying on the table, holding both ends.

"Trace, on." You chant, driving the hot spike down into your body.

"Hmm, this is interesting. Looks like he's either bypassing his circuits or doesn't even know his crest is there. I will need to teach him .. in bed." Caster thinks to herself as she hugs you tightly.

"Reinforcement complete." You say as you open your eyes to an extremely impatient, irritated-looking Rin. "Are you finally done yet? How useless is that?" She asks annoyingly as she snags the pencil out of your hand. " It doesn't even look different, I bet you it breaks all the same." Rin huffs as she tries to break the pencil in between her hands. And nothing. Rin grunts and groans, "Come on, stupid pencil, break!"

More groans of effort and cursing are heard from Rin as she tries to break the pencil by various means, failing each time. "Looks like she'll be at that for a while. Come now, my dearest husband, let us abscond to my secret, soft place. I have much to show you."

You nod. The sounds of a highly frustrated Rin continue to eminate throughout the house as you are lead towards the entrance of your room.
