Previously on message boards, people have indicated that they would like to see Tessa and Charlie partner up. I actually think that Scott and Meryl would be an interesting combination. I think that Scott is underappreciated in terms of how he dances with Tessa. Although off the ice he has an outgoing personality and likes to ham it up - on the ice - he does an excellent job of partnering. And I also think that Meryl is underappreciated in terms of connection to the music. Out of the 4 dancers, I actually think that Charlie might have been better suited for singles.
ETA: I think that Charlie is a great skater!
