Even though Liam was the one to make the suggestion for Mr. Malfoy to come to his home/business to talk about the man's idea.  Once the letter had been sent off, Liam got nervous.  Truthfully, no one had actually been in his flat, but himself, an owl or two, Johann was there maybe once, but no one else. 

So here he was, after making sure that no one was downstairs, he was in his flat obsessively going over things to make sure they were clean, or put in their rightful place.  Liam knew that it was weird, but at this point he didn't care.  He was going to try and make a good impression upon a potential business partner.

After he had gotten things the way he wanted them, he looked in his small kitchen and briefly wondered if Malfoy would drink tea or coffee, before making some of each, realizing that he was going a bit too far by the time he had fixed a plate full of small finger sandwiches, and poured out the boiling water for the tea in the sink and placed the sandwiches in the fridge.

He kept the coffee, Liam felt like he was going to need it as he heard the telltale sound of someone apparating and with one final glance around his flat, he descended the stairs to greet his new - maybe - business partner.

After Draco received the reply from Darrow to just come over whenever that day he felt comfortable in doing so, he immediately put any potions he could in stasis, as he didn't want to ruin them, and quickly finished the ones that would not last.  That took him a good twenty minutes before he was done, and then another half an hour to clean up the mess from the one cauldron that decided it didn't want to be ignored, okay a spider fell from the ceiling into the potion and it exploded. 

Mumbling about ruined potions, Draco left the basement lab and locked it behind him.  His sarcastic house-elf wasn't happy that his master insisted on cleaning the lab himself, but after a direct order, he could not do anything about it.  Draco slowly walked through the house as he thought about whether or not Darrow was going to accept his proposal.  I mean, he could just go to any apothecary and either buy the ingredients to brew things himself, or buy them already made. There was really no need other than Draco's almost obsessive need to try and battle the bad things he had done during school with something good.

As he climbed the stairs, Draco hoped the man would give the money to some worthy cause.  Being a Malfoy, even after being fined after the war, meant that he had money to spare and he really didn't need and/or want any more.  Having a lot of money was one of the things he had argued about with Astoria.  She wanted to spend it and well, he didn't.  About the only time he didn't object to her spending his family fortune, was when she was buying something for Scorpius.  He never thought that he'd be lucky enough to have a kid, but now that he had one, and even though his son was almost 5 or 6 years old now, he still had an irrational fear that he was going to turn into a sadistic madman like his father was at times.

Upon reaching his room, he cleaned himself up fast and then changed out of his potion brewing clothes and into a decent pair of slacks and a dark green shirt.  Draco didn't want to wear  business clothes like his father would have, this was meant to be informal and as he apparated out of the manor, he hoped that Darrow wouldn't mind.
