Are some of our all-time favorite TV characters getting ready to say goodbye in May?

The eighth season finale of Grey's Anatomy includes pivotal scenes at the airport. We know because of a series of photos that have surfaced on Twitter, depicting what appear to be emotional farewells.

As we previously reported, Shonda Rhimes hinted that the season ends in a way that could accommodate any number of cast departures, with the original stars in the eighth and final season of their contracts.

It's too early to speculate who, if any, might be on the way out, or if the cast members even know yet. It's very possible the script is intentionally open-ended, given the uncertainty of Season 9 contract talks.

That said, take a look at these Twitter pics of the season finale and comment below:
