The Vampire Diaries Season 4 is on hiatus until April 18.

But TV Line has given fans something rather significant to ponder in the meantime.

The website confirms that Steven R. McQueen will return to The CW drama at some point this spring, though the form he takes is still unknown.

Might Silas pass himself off as the deceased younger brother of Elena? Or might The Other Side be destroyed and Jeremy join a number of other returning characters in Mystic Falls this May?

My guess: considering The Originals is all but guaranteed to be picked up... and it would mean a rash exist for multiple regulars... The Other Side will, indeed, be removed, paving the way for Jeremy and others (Lexi?) to rejoin the series for Season 5.
