Jessie was Pam's assistant, and there are reports of him accepting authors who had originally queried Pam when he became an agent. Not sure why he's not on D4EO's website yet, but Manuscript Wishlist has his submission guidelines, and his twitter says he opened to queries in May. He wants a query, synopsis, and 10 pages.

His profile says "he/him/Mx. Devine." I suggest using the latter in queries (if you go the Mr./Ms. route, as I do).
