Neal/Baelfire's (Michael Raymond-James) introduction to the world of Storybrooke has huge implications for a lot of characters on Once Upon a Time. We're already starting to see what it means for Emma (Jennifer Morrison), Rumplestiltskin (Robert Carlyle), and Henry (Jared Gilmore), but we've yet to hear a peep from Regina (Lana Parrilla) about the fact that her son's biological dad is back in the mix.

The news that Neal is both Henry's dad and Rumple's son should be big for Regina. It means she has two more people who could pose a threat to her reunion with Henry, and one of them, Rumple, is an old enemy. However, although she's seen Neal, Regina's shown no response to his presence.

What's the deal? Did someone already fill her in on the details? Some fans are worried that we've missed out on a big moment, but based on a new tweet from showrunner Adam Horowitz, that's not the cast.

When a fan tweeted at Adam asking if we're not going to see Regina's reaction to the news that Rumple is Henry's granddad, Adam replied "Why [do] you think you won't see that?"

It sounds like we can assume Regina has been too busy dealing with her own issues to really register that Neal is around or wonder who he is. We're not sure if that's entirely satisfying, but it's better than missing out on Regina finding out the truth!
