Hmm so the narrative has now shifted to... "We were on a break!!" haha. How very Ross and Rachel. Source goes on to say, they have reunited, and might get back together. Or they never split to begin with, and it is just over sensationlised.
Anyways. Who knows what well happen with Jugghead or Bugghead in Season 4. They were very strong and solid last season. With that ominous tag at the end of S3, it is up in the air. The show did say they would explain that early on.
