In the spirit of Magnus Trask's offerings, how about these offbeat pairings for Julia:
Julia and Sam Evans:
Sam falls for Julia, and decides he must lay off the booze long enough to paint her portrait. Julia eventually discovers Sam to be the bastard son of Charles Delaware Tate. Tate's magic has been passed on to Sam, so Julia will live eternally as long as her portrait remains intact. Meanwhile, Maggie has flashbacks of her potential step-mother hypnotizing her with what appears to be a Duncan yo-yo dipped in green glitter.
Julia and Phillip Todd:
Julia reveals her unquenchable thirst for acquiring antiques by secretly poisoning and killing Megan Todd, comforting Phillip after Megan's funeral, eventually marrying the widower, and then locking him in "the room" upstairs while she changes the shop's name to "Hoffman's Hideaway." Years later, she makes a mint selling the inventory on E-Bay.
Julia and Sky Rumson:
Angelique is spitting tacks when she finds her new hubby embroiled in a passionate affair with everyone's favorite redheaded doctor. Julia convinces Sky to gaslight Angelique, prompting the reformed witch to wind up in a strait-jacket at Wyndecliff, while Julia redecorates the Rumson home on Little Windward Island in Chinese Modern.
