I believe Chase was originally Ryan's secret Latin lover Guillermo but a fire sent him to the hospital with horrible burns and he got plastic surgeory that turned him into a tall skinny white boy. Dismayed at the loss of his beautiful muscularity, sexy tan skin, and beautiful blonder hair he fled and changed his name to Chase. Oh Rain how can you be so foolish! HOW CAN YOU NOT RECOGNIZE THE LOVE OF YOUR LIFE GUILLERMO!!!!
