After using a spell designed specifically to scan and "print" physical information on Jack, the other members of the British Peerage learned that the Devil/Ghoul-hybrid had several bruises throughout her body, most of which were centered around her stomach and back where her tentacles came out, in addition to suffering a severe case of malnutrition. Something that not only made them very angry but also set up something resembling a diet plan for Jack in order to make the Pawn recover from said malnutrition. This would normally be very difficult to do since normally the only thing a Ghoul could eat was human flesh, but fortunately for everyone involved, Jack was only part-Ghoul. Enough to have all the strengths and none of the weaknesses of being a Ghoul, namely not being limited to only being able to eat human flesh but other, more normal, food as well.
According to various sources, Ghouls were one of the toughest species in the entire Supernatural World. Extremely high Magic Resistance, incredible strength and nearly instant recovery. They were also known for having the strongest digestive system and strongest jaws in the entire Supernatural World, being capable of biting through and digesting bones with no problems whatsoever. Some had even been documented of being able to not only bite through but also be nearly unaffected by eating metal. Another thing that all Ghouls possessed was an (or in some cases, a set of) additional retractable limb(s), which in Jack's case was a set of four tentacles-like appendages originating from her lower back, each one being roughly two meters in length with a barbed tip similar to the head of a spear.
Anyway, the so called diet plan that the Peerage had set up for Jack wasn't really a plan at all, but rather just letting her eat as much as she wanted, only stopping her when she appeared to risk choking on her food. What surprised them was that she had very good table manners despite practically going into what was essentially a feeding frenzy every time she was at the table. She was much more gluttonously than Ron Weasley, but still had better manners than him. And since being a Devil actually made indulging in the seven deadly sins a good thing, no one in the Peerage bothered to try and stop the gluttonous Pawn.
When the first task of the Triwizard Tournament finally arrived, most members of the British Peerage could be found amongst the audience, waiting for the task to start. Jack was the easiest one to find out of the four Devils in the audience with the other three sitting rather close by the Devil/Ghoul-hybrid. The reason Jack was easily found was because of the rather comically large pile of food, snacks and other various kinds of treats the gluttonous Pawn had brought with her. And said pile was slow but surely shrinking. The fact that pretty much everyone except the other Devils were slowly but surely moving away from Jack out of either disgust or worry was something that Jack was happily oblivious of while the others were merely intentionally ignorant of it.
Over at the tent where the champions were being held, Lilith had just had her wand "weighed", or in other words inspected. Out of the four people participating, her wand was certainly the most unique one, and surprisingly the oldest one as well. Lilith's wand was a total of thirteen inches in length. Its handle was shaped like the king piece in chess with the rest of the wand having a smooth wavy shape, like a snake or a flame. Despite the fact that it was made of olive wood found in Ancient Greece, it was almost pitch black in color even though it was actually a very dark shade of brown. But the unique thing about the wand was its core, a feather from the wings of an angel (and Lilith privately believed that the feather came from her ancestor, Azrael).
By the time it was Lilith's turn, it wasn't the boom of a cannon that signaled it. But an extremely loud and surprisingly well-timed burp that somehow caused a minor earthquake, probably Jack, who the Peerage rather quickly discovered had a minor issue with controlling her bodily sounds, pretty much everything except sneezing for some reason was always very loud and a burp didn't really mean anything whereas a belch meant that she was satisfied. And since it was just a very loud burp, it meant that she was still hungry and therefore still eating. The Devil/Reaper-hybrid couldn't help but simply release a chuckle of amusement as she left the tent and entered the arena.
Back amongst the seats, the Peerage watched in anticipation for their king's turn. All of them had taken something from Jack's pile of food and were chewing on something. The cats were sharing a large bucket of popcorn (which was actually just one out of the five Jack had brought with her, three of which she had already devoured), while the Sword-Devil was chewing on a chocolate bar. At the moment Jack was currently busy devouring a bucket of chicken legs, including the bones. It was when Jack had just taken a bite straight through (including the bone) the last chicken leg that Lilith entered the arena. And then Jack found herself getting a stomach ache, clearly having a bit too much to eat, which considering that she's part-Ghoul actually meant that she had eaten way too much food. After cleaning her hands and lips, she was out like a light the very second her head met Hermione's lap, sleeping hard enough to be completely oblivious to the action taking place in the arena. When the Pawn finally woke up due to being gently shaken by Hermione, the action was already over. Apparently Lilith had given the audience quite a show, if the sheer amount of cheering was anything to go on. Despite the show, Lilith was still placed fourth in the tournament, but she didn't really seem to be bothered by it.
With the first task of the Triwizard Tournament complete, only two tasks remained. Something that the king of the British Peerage did and simultaneously didn't look forward to.
