“The Young and the Restless” viewers weren’t exactly thrilled when popular actor Billy Miller announced that he would be exiting the role of Billy Abbott, but the rough waters were mostly calmed when former portrayer David Tom (brother of “The Bold and the Beautiful’s” Heather Tom [Katie Logan]) swooped in to take back the role. It’s been a fairly smooth transition for most viewers, but jumping into the middle of such an intense storyline — the death of Delia and having been outed for cheating on Victoria (Amelia Heinle) —was a bit of an adjustment for the actor!
