Tonight, "Grey's Anatomy" Season 13 gives fans #JapriltheSequel. Season 13, Episode 16, "Who Is He (And What Is He to You)?" airs Thursday, March 16 on ABC, as another standalone episode for co-parent exes Jackson Avery (Jesse Williams) and April Kepner (Sarah Drew).

Sarah Drew already told Moviefone it's a "pivotal" episode. The promos revealed that Jackson has found his "long-lost deadbeat dad," and although that casting is still a secret until the episode airs, the daddy drama will play out over the episode.

"[April] realizes from the beginning that something's going on with [Jackson]. He's unusually cross with her — even in terms of their working relationship," Sarah Drew told TVLine. "So when she discovers that [the reason] is his father, it kind of opens up a world for her of, 'Now everything makes sense' — his attitude, his shortness, his shutting her out."

It gives April more patience with Jackson, and prompts her to do what it takes to get him to confront his father. Drew said she loves the way the scene plays out, because April tells Jackson he needs to talk to his father because he can't do his job right now and she needs him to do his job. "That's really tough, and I don't think it's completely honest," Drew said. "I think [she does it] totally out of love, but she's not going to let on that it is, because... that's exactly what he needs to hear in that moment. She's so firm and so strong. She's really being a rock for him."

Drew said "a great healing" comes out of the experience and it should give Japril fans "a lot of hope." So what more can you ask for than that?

We've already seen photos and synopses for the next two episodes after this one, so here are the details on "Till I Hear It From You" and here's more on Ellen Pompeo's directorial debut in "Be Still, My Soul."

"Grey's Anatomy" airs Thursdays at 8 p.m. on ABC.
