Yeah, don't worry about it either way. It's not a big deal.

Amy is inviting the captain to Thanksgiving dinner she's hosting. He says he's coming, since his husband (he's gay) is out of town. She:
-- [extremely excited] Cool! Whatever. [trying to seem indifferent] Yeah, don't worry about it either way. It's not a big deal.
Brooklyn Nine-Nine, TV series

1. I'm not sure what "either way" goes with. With what comes before it, or after it? Shouldn't there be a comma after "it"?
2. Does she mean "your coming is not a big deal" or "the dinner is not a big deal"?
Thank you.

'Either way' here means 'whether you come to my dinner or you don't'.

Thank you. So, the "it" in "it's not a big deal" refers to "your coming"?
