LATER
NOISY
COUGH
DOUGH

As I said before, if I don't get a hit on the first word, I will usually use NOISY for the second. So when I only got the green O in the second position on the second word, I know there is still the U that hasn't been used. So I'm thinking it could be a -OUCH word or a -OUGH word, so why not use the OU along with the C and the G to cover the bases better? So then it could have been DOUGH or BOUGH, but at least I'm not going to run out of room.
