Where did we go?
Put your hand down
I'm scared to know
What I'm feeling, yeah
Say yes or no
Do I give up and just let go
Or keep on dreaming?

He watched Zoe from his position in the staff room, the way she walked around unaware of the people watching her and how in a zone she was when she was treating patients had put him in a zone. The dress she was wearing hugged her figure in all the right places, making Max desperate to tell her how beautiful she looked and how much he loved her. Sometimes when he looked at her, it felt like his heart could burst with pride and love but she wasn't his. He couldn't tell her all of these things as they weren't together, maybe once upon a time it could have worked, but not now. Zoe's mixed signals made everything ten times harder, leaving him confused, he wanted her and she knew that, every so often she'd give him a glimmer of hope just to keep him hanging on and now Max was convinced that she was just being cruel to him.

Is this love, can you tell me?
I've had enough
Oh, so tell me

How can I be your lover?
Stop turning me down
One day when you discover,
How bright I try to love you now
I won't be around
It's too late
You're lost, I'm found

He walked away, back to work but more symbolically he was walking away from Zoe once and for all. He'd done his best, he'd fallen hard for the older doctor he'd even been ready to give up him womanizing ways in favor of settling down with Zoe. One day she would realise what she'd lost when she'd given up Max, when she'd realise the life she could have had. Gone were the days where he'd chase Zoe Hanna around, waiting for her to fall in love with him. He was banishing her to the back of his brain and trying to do the same with her in his heart, today was the day he was leaving Holby for he could not be around her and stand a chance of moving on.

I gave my all
Guess you knew all along I would fall
For your teasing, why?
And no matter what, I won't go back to who I was

To some it would look like he was being pathetic, leaving over a woman, but it was the only way. Zoe had infiltrated every part of his life, leaving him not sure how to fully function without her, he had to go cold turkey and completely give up on her because he wasn't sure how else he'd get over his addiction to her. He'd given his all to something she considered a bit of fun, leaving him heartbroken.

It's too late, your loss I'm found
