ABC has released the synopsis for the fourth episode of Grey's Anatomy Season 9.

What can we expect in "I Saw Her Standing There," airing Thursday, October 25?

• Richard calls on Dr. Catherine Avery to help him perform a complicated procedure, as things continue to heat up between Jackson and April.
• Aware that Derek might never operate again, Meredith stops talking about the surgeries she's performing.
• Arizona's struggle to accept her fate forces Callie and Alex to face their guilt.

Grey's Anatomy is off this week due to the vice presidential debate, but returns next Thursday with "Love the One You're With," followed by "I Saw Her Standing There."
