Here is a Moodboard and some of my personal headcanons for the middle Mellark brother (whom I headcanon is named Wilhelm)
-He was born 3 years into his parents marriage, and a year before Peeta
-Wilhelm was the brother on the wrestling team along with Peeta
-He was by far the most rambunctious of his siblings (which frequently got him into trouble)
-He definitely called out his mother’s hypocrisy and sanctimoniousness on more than one occasion. Particularly how she looks down on Seam folk but acts no better than she believes they do. This obviously got him beaten, but he thought he was worth it, if only to see the look on her face
-The reason he joined the wrestling team is because it allowed him a release of energy he couldn’t get anywhere else
-The other boys on the wrestling team called him ‘Willy’. His brothers occasionally used this nickname as well, in the few close/bonding moments they had growing up.
-Wilhelm frequented the slag heap (unlike his brothers) which he was able to charm his way into time and time again. The girls in 12 definitely liked him.
-His name mens ‘resolute protector, and his older brother’s means ‘defender/protector of men. This is ironic, because neither of them ever protected Peeta. The reason they weren’t particularly inclined to do this is because Mrs Mellark often pitted the brothers against each other and created a very ‘every man for himself’ type environment growing up. Because of this they were never able to be very close growing up
