This happens during Season 2 Episode 4, Enjoy.
"Go! Go!" Sabine shouted as they were being chased by two inquisitors.
The Seventh Sister used the force on Ezra to restrict his movement, and her probe droids pulled him towards her.
"No!" Sabine shouted. She ran towards him in an attempt to save him, but had other ideas.
"Sabine, run!" Ezra shouted at Sabine, before shoving his lightsaber into the control panel, closing the door.
Sabine's POV
I watched as Ezra shoved his lightsaber into the control panel and closed the door on me, he sacrificed himself for me.
I fell to the ground, beginning to cry up against the cold metal door, I don't know why, but I felt like something in my heart was missing. I couldn't deny my feelings anymore, I loved Ezra, I was kinda sure if he loved me back. Yeah he tries to woo me all the time and I kept denying and rejecting him.
I can't believe I kept rejecting him, I just want to hug him, and when I rejected him, he would walk away sadly, facing the ground, it pained me so much so see that, I wanted to just run up to him and kiss him.
A Few Minutes Later...
Ezra's POV
I watched as the new inquisitor walked in with Sabine at his side, pushing her down next to me. I just wanted to grab my lightsaber and gut right there and then, but I knew that I wouldn't stand a chance fighting them alone.
I looked across at Sabine and noticed her cheeks were glistening. Had she been crying? Why?
I couldn't resist my emotions anymore. I lifted my hand up and stroked her cheek, she looked up at me questioningly.
"Ezra what-" she said, before she was silenced as I lunged forward and kissed her strongly and passionately.
Sabine's POV
Ezra lunged forward and kissed me. Ezra is kissing me! I thought, I wanted to give him all the love I had to offer, so I shifted over a little and laid on him, still kissing passionately.
I suddenly realized who we were making out in front of. The inquisitors were just standing there, watching us. I felt a little creeped out, especially from the Seventh Sister. Even though she's an Imperial, she's still female and she might be getting some enjoyment from seeing me and Ezra kiss.
Ezra's POV
I watched helplessly as The Fifth Brother took out his lightsaber and held it next to Sabine's neck
"Contact your rebel friends and bring them here" The Seventh Sister demanded.
As much as I wanted to say no I couldn't or Sabine would be killed, and I couldn't allow them to do that, especially not now, after she kissed me, I need to feel her warmth properly, without some creepy Imperials watching. If it wasn't for them, they probably would've had sex, but they couldn't in front of annoying inquisitors.
I raised my arm to call Zeb...
