Being prefect wasn't just having a good time though, it meant extra work too, which, he supposed will be a piece of cake for the Slytherin. Speaking of cake, he should've asked one of the elves to bring them cake, but...yeah, he was watching his diet. He'd offer of course, but that will ruin the taste of the tea.

Nonchalantly raising a brow, River found him amused with Paul and just...let him carry on being...Paul. "You're being stingy Paul. You should've given the boy 5 points at least," for not exposing him and being loyal to the deputy headmaster. "Mint for you both, got it." River plucked more mint sprigs, and went back to his tea apparatus. "I got this set of leaves dried earlier..." he said pulling out a tray from underneath the table and started to slice it into four parts, "White tea needs to be dried naturally, but since we don't get much sun, I had to use magic to do the trick." River filled the tea pot with water, and charmed it to boil. After a few minutes of cooling it down a bit, he dumped the chopped leaves inside with the mint sprigs, "With white tea, it is important not to over steep it. The tea will taste bitter if we're not careful." He said glancing at his watch, "Four minutes would be enough to get the full flavour." River subconsciously took a deep breath while Paul was busy watering his plants. Nothing beats the smell of earth because wet earth means outdoors.

After four minutes, River took out cups from under the table and started to pour the golden liquid into it, offering the first cup to Oliver, and then to Paul. "I would love to stay and chat but I have things to finish inside," he said pointing towards his office with his thumb. "Do enjoy your tea, gentlemen. And...you may take fresh tea leaves with you." he said with eyes twinkling. "Thanks for watering my plants, Paul." he said as he finally turned and went back to his office.
