Fiona flinched at Ewan's words, pulling away slightly. She couldn't believe he had just accepted his want for Athena.

She watched him revert to his signature cool facade, and knew that if she did nothing at this time, she would lose him forever. 

Fiona shook her head subtly. Yes, Athena's clutches were knee deep into her man, but she would never give up! She has come too far for Athena to have him all to herself!

So, she suddenly leaned forward, almost as if she wanted to grasp Ewan, to pull him back into her orbit. "I can show you that I can change! Just stay with me, Ewan! I'm also in your past!" 

Fiona was ready to be termed frantic and desperate by Ewan, so long as he bought into her words!
