At home Elizabeta pondered the events of the previous evening. After his walk Lucas had returned composed and assured.

He'd told her that he thought they might be able to try to work things out but that they would need to take it slow, that they didn't really know each other any more and that the situation was more complicated than she imagined.

It was not what Elizabeta had been hoping to hear, but it was a start. She was certain that, given time and circumstance, she could persuade Lucas that she was still the only one for him.

"I want us to try," she replied passionately, "please let us try."

Lucas had nodded. "We will," then added," You'd best go now – it's late."

Elizabeta looked at him for a moment, "I – I don't have a home to go back to," she said softly, thinking of that last angry scene with her husband just minutes before she'd stormed out and picked up her phone to call Lucas.

"Oh," said Lucas, taken aback by her comment, "well, I guess you'd better take the spare room then."

She had and found she'd slept soundly that night.

Though she'd found bread to make toast for breakfast, Elizabeta had discovered Lucas's kitchen was not as well stocked as she had hoped. Having found nothing suitable for lunch she'd given up on the idea of making it and decided they should eat out instead.

By 12.15 she was becoming impatient. She picked up her phone and dialed Lucas's number.

"Where are you?" she asked impatiently. "You said you'd be home by 11.30."

"Victoria Station," came the reply.

"Oh," she replied. "I thought you were at work."

"I am," he replied shortly.

Elizabeta put down her phone. She sighed to herself, deciding she had had enough waiting.

She arrived at the station twenty minutes later and sent a text message to Lucas telling him to meet her outside.

"Elizabeta," he started when he'd arrived outside, "you know you shouldn't be here – I'm working, I can't talk now."

"That's ok, I'll wait," she said smiling, "once you're done we can go to lunch."

"Elizabeta," he said, pausing to take in a breath, "I think I made a mistake last night – I think I knew the truth but I've been afraid to admit it. I don't think we can go back to being the way we were – everything's changed. I'm not the same person I was then, I don't know even know if you are." He paused, then looked at her, "I don't think we have a future together - I'm sorry," he said, gripping her arm gently.

She brushed him off angrily, "You used me – you used me to get what you wanted and when I can't provide you with any more information you want to dump me. I don't even have a husband to go back to anymore because of you. Well, I'm not giving up on what we had – I don't care what you say, you know I'm still your wife – your real wife. That must count for something."

"Elizabeta, I'm sorry," Lucas said gravely. "It's over between us, it has to be. There's someone else and I have responsibilities. I'm going to be a father."

She stared at him, her face enraged, "Who is she? Who is she then – answer me!"

"What does it matter? You don't know her – she's just someone I know from work," Lucas said coolly.

"That Ros then? Is that who?," Elizabeta said almost spitting out her name. Lucas didn't react. "Or that other one," she continued, "that blonde one, the young one – she must be a little tart," she finished viciously.

She could tell from Lucas' angry expression that it was the other blonde one. He said only, "It's over Elizabeta," then turned and walked away.

After a moments shocked silence, Elizabeta followed to confront him as he stood surrounded by his colleagues in the middle of the station.

"You used me Lucas. You ruined my marriage and now you want to abandon me," Elizabeta whispered bitterly then raised her voice and said loudly. "And all for what? For some little whore you hardly even know you managed to get pregnant," her gaze narrowed as she glared at Jo. "God knows how you're considered smart enough to work for MI5 when you haven't even heard of contraception, apparently."

"I have no idea what you see in her – she's doesn't look useful or intelligent or even especially pretty," she said loudly as she continued to glare at Jo, then she continued passionately, "I know you Lucas, I love you, I've always loved you."

She appraised Jo coolly with a dismissive glance. "How could she know you like I do? She couldn't understand what you've been through. What would she know about life," she said derisively. "She probably doesn't even care for you and you'll just pick her up and put her down again once you've had your fun."

Lucas grabbed Elizabeta and pulled her away from the crowd. "Don't presume to know her or to understand what I feel for her," he hissed angrily.

Left alone in the center of the station while her colleagues edged away from the scene in search of a more discreet location, Jo felt her legs freeze and thought she would surely die from the embarrassment of the combined stares of her colleagues and curious passers by who had stopped to observe the unfolding drama.

The ringing in her ears that had started a few seconds earlier was becoming louder and was followed by a sudden wave of exhaustion and a curiously light headed sensation. Lucas turned to see Jo collapse downwards in a graceful motion that reminded him of a bird suddenly bereft of breeze to support its flight.

Lucas immediately released Elizabeta and rushed to assist Jo, who lay motionless on the ground.
