There are just so many delightful moments. From Lana Parrilla forgetting her lines...
...to Sean Maguire's views on parenting.
Amy Manson laughs in the middle of a scene three times in a row, it's adorable.
And Jennifer Morrison pulls what is, very possibly, the Greatest Face Ever.
But nothing, in this video or in this WORLD, is more delightful than watching Colin O'Donoghue lose it.
And he loses it a lot.
But he owns up to it.
He dances it out.
And he carries on.
He's got the heart of a hero, this one.
