Isaac quotes from Teen Wolf

Just out of curiosity, do you remember the other night?

Isaac

[confused] You mean the night before last?

That night before you weren't you.

Isaac

Yeah, I remember.

So, that night... were you you, or were you not you...?

Isaac

You mean, the night when we were us?

Yeah. I just wanna know if... if it was actually you with me.

Isaac

...did you want it to be someone else?

[laughs nervously] No. No. No, of course not.

Isaac

Good. Because it was me. And, I do remember it. I really remember it.

Stiles

[about Meredith] Okay, will you just let me handle this, Isaac? Please? I just... I have more experience with banshees.

Isaac

Yeah, and mental patients.

Isaac

All right, I'll say it-- you look like you're dying. You're pale, and you're thin, and you look like you're getting worse. And we're all sitting here thinking it. When we find the other you, is he gonna look like he's getting better? What happens if he gets hurt?

Stiles

You mean, if he dies, do I die? I don't care. Just so long as no one else dies because of me. I remember everything I did, Scott. I remember pushing that sword into you. I remember twisting it.

Scott

It wasn't you.

Stiles

Yeah, but I remember it. You guys gotta promise me-- you can't let anyone else get hurt because of me.

Scott

We've done this before, guys. A couple of weeks ago, we were standing around just like this, and we saved Malia, remember? That was a total stranger. This is Lydia.

I'm here to save my best friend.

Scott

[looks at Stiles] I came to save mine.

Isaac

... I just didn't feel like doing any homework.

Argent

I appreciate the concern, but you don't have to stay. I'll be alright. I've dealt with this before. I have a capacity and an ability to compartmentalize my emotions.

Isaac

[turns to him, tears in his eyes] I don't.

Argent

[confused] Why would she make four of these?

Isaac

[in realization] She didn't. She made five. She made the first one, and then she figured it out. She used the first arrowhead to kill one of the oni. We saw her do it.

Isaac

[about the oni] What if silver is like a poison to them? What if it needs to stay in the body? What if that's what she was trying to tell you, that she'd figured it out?

Argent

These four would still have been setting when she went off to meet Scott...

Isaac

We could stop them.

Argent

[determined] No. We can kill them.
