Here is my vision on Larry;

He will appear late Summer and the Aliens is connected to Gene.But Salem hasn't seen them since 1986.It has been almost 18 years they been gone.But I believe it has to do with Stefano.

 

In the will it said Lexie get's all the money and Colin saids he is a DiMera and someone colse to Gene dies,that someone gets the Bradford Curse and Chole gets it,and Kate will say she married Stefano 18 years ago.

 

So Salem Get Ready for The Secert Door.Because you don't know who has been in it.Hint someone in Salem knows who been hiding in there.
