As the Castle is large, the tens of soldiers that Ryden has invited can stay in a room alone
The castle at least have that much capacity. As such, it was not hard for Ryden to sneak in one of the rooms of his comrades without the other soldiers knowing
The first target of Ryden was the soldier named Groove
If David was his bestfriend among all of the soldiers that became his blood brothers then Groove would be his secong closest friend
Groove has a body that is different than most of his colleagues
While the other soldiers are big and bulking with muscles, Groove is in the skinnier side
Of course, it doesn't mean that Groove is really skinny or something. He just looks skinny when being compared to the other soldiers
While the 'proper Knights' that have the backing and teaching of their families, the poorer commoners are different
