Thursday's episode of "Grey's Anatomy" will see Owen and Amelia taking the next step in their relationship. The on-again-off-again couple is currently in a good place and it looks like they'll have a serious talk regarding the future.

"Owen decides he's going to take a huge step," actor Kevin McKidd revealed to TVline. And that "kind of leads them into a conversation about, 'What is the future for us?'" Without revealing what the huge step is, the actor hinted that fans of Amelia and Owen would really be pleased by the events of "At Last" as it involves a "really beautiful and romantic" scene.

This has sparked rumours that Owen will propose to Amelia, but according to some fans, the huge step could be Owen finally moving out of the trailer and the duo getting a place of their own.

Elsewhere in the episode, we'll see Callie and Arizona still struggling in the aftermath of the arrangement that saw Arizona getting full custody of Sofia. Callie is devastated, and it remains to be seen how this will affect her relationship with Penny.

Meanwhile, actor Jesse Williams has given fans hope of a reconciliation between his character Jackson and Sarah Drew's April. "Jackson and April know each other better than I think anybody else in this world," the actor told TVLine. "They've been through so much and have seen each other at their highs and their lows, so even though they're divorced, they're still clearly each other's person.

"They definitely have hope," Williams said. "I think, as long as they're alive, they're going to have hope, because they care deeply about each other. I would be hard-pressed to ever say the slate is wiped completely clean."

"Grey's Anatomy" airs Thursdays on ABC.
