Despite his apparent resistance, Sandra already knew that Timmy would be heading out to meet with his ex at midday. It was too predictable that he would, so arguing with him about it when she already knew the decision he was going to make was just a waste of time and energy.
Alexander himself knew that Timmy would show up, or he wouldn't have even bothered having the letter delivered to the apartment. Whether Timmy was showing up in anger to hear what was going to be said, or if he was turning up because there were still feelings there, Alexander didn't care; he was just glad that he would be getting to see him again. The last few days hadn't been great for him. He'd been arrested and, for a while, had the whole country at his throat. When it came out that he was 'innocent', everyone seemed to jump back on board, either apologising for their quick judgement, or claiming that they knew he couldn't be a monster as previously depicted in the news. His business hadn't been badly affected; it had a surprising boom, in fact. Just because everything was back to normal and he had escaped jail wasn't to say he was okay. It had an emotional toil on him, but he knew how to put a face on and pretend, which was precisely what he had done all that morning as he returned to work for the first time.
When Timmy did show up, nobody on the top floor of the company's building really understood why he was there. After all, Timmy was one of the people involved in Alexander's arrest; he was the person who was heralding all the talk of murder and violence, which all seemed to now be false. Nevertheless, he was shown to Alexander's office and greeted by the designer with a wide smile.
"I knew you'd turn up," he smiled, stirring a sugar cube into his tea and gesturing for the other to take a seat, before fiddling with his tie to ensure he looked perfect. Arrogantly, he knew it didn't take much effort to achieve that. "...I'm glad you did, though. I wanted to see you."
