Kat was pretty much glad of this teamwork thing and that none of them complained about this task just yet. Not like Kat was gonna complain though because they had a house elf to help. Complaining wasn't necessary when you decide to lend a hand to someone/something in need. "Thank you," she replied to Lex and then checked the time. 5 minutes already. Okay, good. Kat took her wand out first to lower the temperature. Like... she could use water to lower the fire and as well as the temperature right? That worked? "Aguamenti..." she said, focus much on the intent which, for her, would be a little but less than normal, and did the hand movement which looked like an S lying down. She sprinkled the water a bit on the fire under the cauldron, which let the flame lessen too. That would lower the temperature, yeah? "Finite." It was a lower flame now, lower than before.

So... she was gonna let that simmer for a while. Kat waited for a bit and peeped on the ingredients inside the cauldron. Well, it did look simmered enough. The Slytherin held the aloe on top of the cauldron and squeezed it a bit. So ten drops, that was it. One... two... three... four... five... six... seven... eight... nine... ten. Alright, done. Kat set the aloe aside and then peeped again inside the cauldron. "Okay, we'll have to wait again cos we have to let it simmer for not more than an hour." Exact time, she didn't know. The book vaguely stated 'not less than an hour', if she could remember it correctly.

Waiting again. Yeah, this potion took long to brew but Kat would be patient. She leaned on the cave wall as she waited for the potion to simmer for a bit, eyes still looking at the cauldron with their potion brewing. At least no one died in the process of tackling that snargaluff. Kat would like to tackle it again though, just for the fun of it. Dangerous yet fun.

"Uhm... we'll use it after we let the potion simmer, then we light the galangal powder on fire. Wait for it until it looks browned enough and then add it to the cauldron." Kat realized that they were going to be DONE any minute now, and they could finally help the poor house elf. She was excited, did they know? Could the audience SEE?
