One day in Ponyville. Spike was writing a litter to someone.

"That I found out I was barking up the wrong tree all this time. sorry Rarity, I love..."

Until he can finish, Young Autobot came.

Young Autobot: Hi there. What are you doing?

Spike: nothing

Young Autobot: Don't play dumb on me.

Spike: I'm not doing it.

Young Autobot: Yeah right.

Spike: its true.

Young Autobot: Will see

Then Young Autobot left and spyed on him.

And Spike got in a room with no windows.

"Sorry Rarity, I love Applejack"
