Well. Speculation time: From the second scene mostly everyone can safely say that the "covered" characters are Sky and Red. I can clearly see that Sky isn't who he/she seems. Her "fake" alibi on why he/she is entirely fake, getting popularity votes-- and of course being a likeable character. On the other hand Red.. I don't think he is the second person. As it was Sky that asked to get Red. My theory is that Sky and someone else has captured Red, Yellow, And Sky. But I don't understand why sky would get captured when He/she is becoming more suspicous every episode. My main 2 choices have to be White and Red.
1. Red is slightly smaller than every contestant.
2. White hasn't gotten much of a plot/character design "yet" so Now is a perfect time to shine.
Just a speculation, your work is great, keep it up.
