This is after Spencer finds out about Toby being "A". I got this idea listening to the song on the radio.

I miss those blue eyes
How you kiss me at night
I miss the way we sleep

Spencer is in her room with her knees covering her face. She is hurting. When she shuts her eyes she sees Toby's blue eyes. She misses the good-night kisses they share, and the way Toby would always protect her. She misses his warmth in her bed. She misses him,

Like there's no sunrise
Like the taste of your smile
I miss the way we breathe

Spencer looks at her clock. Not even close to morning. She remembers how they kissed. A smile always on his lips, was it all lies? Was it a fake smile?

But I never told you
What I should have said
No, I never told you
I just held it in

Toby lays awake in his bed. Toby should have explained himself. He should have told her why. Not asking how long she knew. He should have told her why. Why he choose –A's side. He should have told her he was doing it to protect her, not harm her. But he didn't, he kept it to himself.

And now,
I miss everything about you
Can't believe that I still want you
And after all the things we've been through
I miss everything about you
Without you

Spencer and Toby both miss each other. Spencer wishes she could get over him. He is with the enemy. He betrayed her. Toby knows there must be a way to make it up to her. After everything that has happened, this ended it. It was a huge lie, but it was to protect her. It was the only way. Spencer misses him. She is nothing without Toby, and Toby is nothing without Spencer.

I see your blue eyes
Everytime I close mine
You make it hard to see
Where I belong to
When I'm not around you

It's like I'm alone with me

Spencer closes her eyes to stop the tears. That does nothing. She just sees Toby's blue eyes. She hates to close them. She's blind without Toby. She can't see light. She only sees darkness. She doesn't have a place without Toby. She feels alone. She has Aria, Hanna, and Emily, but they have a partner. She feels alone, and scared, and lost without Toby.

But I never told you
What I should have said
No, I never told you
I just held it in

Toby knew he should have stayed. He knew that he shouldn't have run off like that. But he was scared to face Spencer. He was on A-Team. The team that has been harassing Spencer and the girls since Alison was found. What if he had told Spencer before that night? What if he had told her in person, not letting her find out? Mona told him they would find out. She was right, but he should have been the one to tell. He kept that dirty little secret to himself. No it is back to haunt him.

And now,
I miss everything about you
Can't believe that I still want you
And after all the things we've been through
I miss everything about you
Without you

Spencer wants him. She needs him. She can't live without him. She shouldn't want him, but they went through so much. One dirty little secret ruined everything. She misses him. She is without him.

But I never told you
What I should have said
No, I never told you
I just held it in

Spencer should have told the girls why she and Toby broke up. She could. She never told. She can't or one of them with be harmed. So she is going to kept it in.

And now,
I miss everything about you
Can't believe that I still want you
And after all the things we've been through
I miss everything about you
Without you

Toby misses Spencer. He would be surprised if Spencer forgives him. He will be surprised if she still wants him. After everything that has happened to everyone, Toby still loves Spencer. He won't stop. He misses her, and he is nothing without her.
