Bonds.

"What do you mean, familiar?" I ask, stepping out of the closet now that my sister has gone upstairs. 

"Her skin, it reminds me of my bodyguard's and best friend's fur." She says, "Oh my...my attackers would have had to had gone through her. That explains why she didn't come back right away on her daily food run. It looks like she had gotten to your sister." 

"Wait, wait, wait. You are saying my sister...kissed your friend? Well this just gets better and better doesn't it." I say, kinda disgusted now. "So now my sister is going to be your bodyguard pretty much." A loud thump is heard upstairs as well as sneezing and coughing. "That didnt sound too good. I gotta go check on her." I say, walking upstairs after leaving the closet. I walk to the left, where my room and my sister`s rooms are across from each other. I peek into my sister`s room to see her lying on the ground, light blue fur all over her body as her hair is a bit lighter than the rest of the fur on her body. It seems her hair is forming into a crest of diamonds, though it retains it does not look like it hardening. She looks to be in pain as her heels crack as she lays on the floor. If she was to stand, she would have to stand on her toes. Her fingers become three and are covered in a darker blue fur. From the sides of her new hair crest grows two dangles, one on each side. 

"I am sure of it now. It is Lydia..." Ryin says as she watches my sister`s transformation through my eyes. My sister`s ears grow long and become pointed at the tip. She lets out a yelp as a tail grows out from her back, an extension of her spine now as it flicks around. The last thing to change was her eyes as they grew a bit larger and became almond shaped, her lens becoming a dark blue while her pupils becoming a lighter shade of blue. She now lays on the floor, breathing heavily. 

I decide to step into the room now and kneel by my sister. "Layla....Layla. You okay?" I ask, poking her as she now rolls over. 

"Wha...what happened...I feel diff-" She then lets out a rather loud scream as she see me, then her own hands turned paws. 

"This is going to be fun." I hear Ryin say to me, seemingly holding back laughter as we both watch Layla freak out over her body.
