Meredith (Ellen Pompeo) and Nathan (Martin Henderson) talked about her well-being. Based on the second video, their conversation looks very awkward. They previously developed their feelings for each other.

But with Megan's arrival, Nathan is now caught between his presumed dead girlfriend and current lover. This only brought more issues when Maggie (Kelly McCreary) confronted him to pick a side already in the third clip.

While Jo (Camilla Luddington) and Alex (Justin Chambers) had a conversation, she and Andrew (Giacomo Gianniotti) glanced at one another.

His estranged wife Amelia (Caterina Scorsone) received a call from Teddy who told her that his sister is alive. It is still unknown if Teddy will become the third wheel between the couple or not. But there is a possibility that she may become a permanent fixture at the hospital because she will join her former ward with Maggie as the head.

The synopsis from Spoiler TV says her research will bring a discovery that will shock them.

Carina might become a hindrance for everyone including her own brother, Andrew (Gianniotti).

Giacomo Gianniotti also told ET Online that there will be some heated exchange between the two siblings from Italy. Her feisty European background might make the other doctors feel uncomfortable too.
