I can't see Alicia coming back to Emmerdale. Yes, her sister Leyla seems to be Jake's mum for now.

Jake is back for teenage storylines with Gabby and Lachlan, to be shown in a while.

I think Nikhil and David's bromance could lead to Leyla being an item with David soon. Jai is still around of course. I wonder if we might get a dramatic love triangle, as we haven't had a new one for, um, seems like several days or so already?
