Not a Carlito fan but he's VERY likable and has the X Factor. He's very memorable and has a really decent voice. With the right songs and image, he might go really far. I don't see that for Rion or Ellona and I think that's why they went home.
Restless Road, should also go for songs that showcase more of their harmonizing because their harmonizing is unbeatable. But vocally, they cannot hold on to it on their own and it's kinda sad.
