Someone correct me if I'm wrong, but since Economy Saver is a non-changeable ticket, by missing your exact return leg, you'll be forced to buy a new ticket altogether.
EDIT: Sorry, didn't get the question right the first time around. Just keep quiet about it and you should be OK. And of course, what I said above still applies.
