When Jonathan called over Xavier it took his attention away from Bella which allowed her to continue eating all of the food Jonathan gave to her. Bella wasn't dumb either and knew exactly what Jonathan was doing and she inwardly thanked him for his help while eating the food as quickly as possible in case he came back a few minutes later.
"Oh he's ready that's perfect timing!" Xavier said with a smile as he walked over to Jonathan. The fact that Jonathan called him specifically to come to look at important things made him feel special and as if he held a very important place of power in the games.
Some of the other people in the room didn't realize what Jonathan was doing and were wondering why he called Xavier of all people but most ignored it since they didn't care about Ezekiel's story anyway.
