CT And Diem's 'Challenge' Cast Members React To Special 'Bloodlines' Tribute

Read the heartfelt messages from their MTV cohorts.

CT made an emotional return to his "Challenge" stomping ground with Diem's "bloodline" during last night's episode -- and their motto of "do it for D" understandably struck a chord with everyone in Turkey as well as those watching on the small screen.

Fittingly, a bunch of the "Battle of the Exes 2" partners' fellow MTV cast members flocked to Twitter to offer their thoughts about CT and Faith's cameo -- and share their personal memories of the courageous MedGift founder. See their reactions below, add your favorite CT and Diem recollections in the comments and be sure to keep watching "Battle of the Bloodlines" every Wednesday at 10/9c.
