Like his twin sister, Raquelle, Ryan knows he's hot. He loves showing off his plastic abs and bad boy 'tude. But this wanna-be musician doesn’t fantasize about taking Barbie down a notch (like his sis does); instead he dreams of taking her out on a date.
He and Barbie are shown to be friends, however, Barbie doesn't know that she's Ryan's crush and still chooses Ken.
He and Ken hate each other and are constantly fighting over Barbie.
According to the Chinese version of Sour Loser, when Chelsea went behind the cutout figure of himself, and yelled at him, she pronounced his name "Lay'an" which the first and only time in the Chinese version of Life in the Dreamhouse his name is pronounced this way, as the R turns into an L in Chinese, the vice-versa of the Japanese language where the L turns into an R.
Ryan and Raquelle have similar roles to Alan and Ann from Sailor Moon, with the exception of being real siblings and not misguidedly evil. Ryan crushing on Barbie who loves Ken is similar to Alan crushing on Serena who loves Darian and Raquelle crushing on Ken who loves Barbie is similar to Ann crushing on Darian who loves Serena.
