When Alice died, I honestly fully expected their place in Salem to be filled by Doug & Julie. That did not happen. Instead, Julie became a snarky, constantly sniping shrew....thankfully that has changed.
I read an interview with Melissa Reeves (Jennifer), who adored and empathized with the character of Alice, and I think she wishes she could fill that place in the hub of Salem. Gosh, I wish Jack could return. But for now, I just am thinking that void is going to be John & Marlena. I think that when John finally returns, he is going to say Bye to ISA, and concentrate on family and friends. But, what do I know?
Every writer has their own ideas, and maybe the suits all think no one is fit or able to be matriarch & patriarch of Salem. That Alice & Tom were it, may they rest in peace.
