To celebrate TGIT night — don't forget Scandal and How to Get Away With Murder have new episodes, too! — we're taking a look back at all of the teaser trailers released ahead of the premiere.

Check out the clips below!

During tonight's new show, Arizona, Miranda and Jo take on an interesting new patient outside of Grey Sloan Memorial Hospital. The trio travel to a jail to help a 16-year-old inmate — serving 20 years to life — deliver her baby. So intense!

The Season 13 winter finale — which aired on Nov. 17, 2016 — left Grey's fans with many unanswered questions. Will Alex really go to jail? Is Jo leaving Seattle? Is Owen and Amelia's marriage really over?! We. Need. Answers!

We can't wait for our girl Meredith to be back on the small screen! From Season 1 — which premiered in March 2005, can you believe it?! — until now, we've followed Mer through her intern years, her residency, her marriage to Derek and becoming a mom-of-three.

Grey's Anatomy returns tonight at 8 p.m. EST on ABC!
