Former Steven Universe Director Ian Jones-Quartey warns fans to not watch the leaked episodes before the premiere of the latest Steven Universe episodes (Stevenbomb). It would seem as though the staff already know the episodes have been leaked out.

Story goes that two episodes of the planned Stevenbomb event coming this January 4th have the first 2 episodes leaked out. Below are the links (while available):

Steven's Birthday

While it is claimed that the leaks may have come from the same person who received the previous leaks for advance screenings in Brazil, it's been refuted by a Reddit user.  Regardless of who has the latest Stevenbomb episodes, much like the previous leaks in the past couple of months, it's only a matter of time before those episodes are already leaked. 

The most recent leaks from Cartoon Network that have yet to broadcast in the US are three episodes from The Amazing World of Gumball - 'The Apprentice', 'The Wicked', and 'The Hug'. All three have been aired in the UK and The Middle East. A fourth episode, 'The Traitor', is currently available for viewing in the US via CN On Demand.
