If you both Efiled and both your returns are Pending, the second filing with a duplicate dependent will be Rejected, unless they filed with an IP PIN. When that happens, the second filer can remove the duplicate dependent and Efile again. Here's How to Get an IP PIN.
If the second filer is actually entitled to claim the dependent, the first filer will need to Amend their return (after their refund has been received) and mail it in.
Here's more info on How to Amend a Tax Return.
