Is Grey's Anatomy gearing up for another deadly season finale?

Deadline confirms that neither Gaius Charles nor Tessa Ferrer have had their contract options picked up for Season 11, meaning they will not be series regulars this fall.

Both came on board on Grey's Anatomy Season 9 and were promoted to full-time status last summer.

The actor/actress could still make guest appearances next year, but Shonda Rhimes is well-known for doing away with characters in a rather permanent fashion.

Case in point: Tina Majorino, who debuted on the series around the same time as Charles and Ferrer, and who was killed off on the Grey's Anatomy Season 10 opener.

What do you think of this casting news? Will you miss Shane and Leah?
