Tall Boy

"Serpents take care of their own."

- Tall Boy to Jughead Jones

"Tall Boy" is a senior member of the Southside Serpents.

Season 1
After the arrest of FP Jones, and his refusal of an offer of a lighter sentence in return for implicating other Serpents, Tall Boy and other Serpents visits FP's trailer to let FP's son Jughead Jones know that they would have his back for as long as FP was gone.

Tall Boy offered Jughead a Serpent leather jacket, which Jughead put on.

Season 2
After Fred Andrews was shot at Pop's Chock'lit Shoppe by an unidentified assailant, Jughead asked the Serpents to investigate the possibility that it was retaliation for some of the Serpents being fired from Fred's construction site.

After learning that a Serpent had been bragging that Fred got what he deserved, Tall Boy and a young Serpent violently interrogated him until confirming that it was just talk, then brought him to Jughead's trailer to let him know. When a horrified Jughead asked why they'd brought the beaten man there, Tall Boy said it was so Jughead could tell FP that they were keeping their promise to look out for Jughead.
