I am – Hercules!!
Jeph Loeb and Jesse Alexander, who (were one to judge from the season-two "Heroes" DVD set) appeared to be Tim Kring's chief lieutenants in the "Heroes" writer's room, have left the show. From Variety:

Both scribe-producers had been with the show since its first season and were known to have led the day-to-day production operation under the direction of creator/exec producer Tim Kring.

Loeb has known Kring since the pair worked together on the screenplay for 1987's "Teen Wolf Too." A comic book writer ("Hulk: Grey," "Spider-Man: Blue," "Daredevil: Yellow") since 1991, Loeb wrote his first teleplay for "Smallville" in 2002 and spent half a season at "Lost" before Kring brought him aboard "Heroes." Loeb scripted the "Heroes" second-season finale, "Powerless." Alexander wrote on all five seasons of "Alias" and worked as executive consultant and co-executive producer on the first season of "Lost" before joining "Heroes." Alexander scripted last week's episode, "Eris Quod Sum." Read all of Variety’s story on the matter here.
