Sam Palladio's Nashville character, Gunnar Scott, suffered a big loss on the last episode of the show. When we caught up with him at PaleyFest yesterday, he told us Gunnar has a rocky road ahead as he copes with the change. We also asked how the death of Gunnar's brother - and a new character who strikes up a friendship with Scarlett - might impact Gunnar and Scarlett's romance.">
