In the most recent episode of Grey’s Anatomy (Season 9, Episode 23: “Readiness Is All”), April Kepner (Sarah Drew) was hit with a pretty big shock -- and so were we. Paramedic Matthew surprised her with a medical-themed flash mob to The Proclaimer’s “I’m Gonna Be”… ending in a proposal. It was totally unexpected, but completely adorable.

It seems like April and Matthew were made for each other, and Sarah agrees. “She started dating the world’s most wonderful guy, who is on the same page as her about their life goals, beliefs, and who they are,” Sarah told The Hollywood Reporter. “There’s so many things that fit with Matthew; he’s been sweet to her this whole time.”

But don’t think we missed April’s glance back at Jackson after she said yes to Matthew. What was that about? “In a lot of ways, she’s not really completely aware of how she feels about Jackson,” Sarah said. “There's residual stuff from what their relationship was as a couple that with the closeness of their friendship and their chemistry draw them together. I don't think she is aware that she's pulled between Jackson and Matthew, even if she is.”

Later, Sarah added, “She is totally excited and committed to being with Matthew and she's still reeling from the joy of being proposed to as the finale starts. Then things happen that make her really begin to wonder if he's the right choice for her. It's pretty intense.”

So even though April said yes, it might not be her final decision? According to Sarah, maybe. “We end the season with her in complete and total confusion and incredibly emotional about the confusion,” she said.  

Who do you think April will choose -- Jackson or Matthew? Sound off in the comments!
