Help Identifying a Possible Poisonous Berry and winning another argument with my wife

[Patronus]

The inside looks very muscadine-like, clear flesh with fairly large seeds. I touched the flesh to my tongue and it numbed my tongue a little.

And your kid ATE THREE?

One of my kids ate a couple of these berries, only a couple so she's OK. My wife first thought they were pokeberries. I told her over the phone they're not and we don't have any poke salad growing in our yard. By the time I got home she convinced herself they were elderberries, which I'm pretty sure is wrong too.
It's a vine growing into a sweetgum tree. I can't find anything on the interwebs that looks the same.

She ate two. They might be sweet, seemed so from my tiny taste but I didn't want to taste again to be sure. Between the wild stuff and what I've planted we have blackberries, blueberries, muscadines, persimmons and figs, not counting the wild onions, garlic and dandelions etc, that I've showed her. She's grown up eating out of the yard and this is the first year I've noticed these berries. I've pulled them out of the tree now, but I normally leave this sort of thing be.

The leaves look similar but are not leaves of three. Each offshoot has 5, 1 on top in the center and 2 on each side spaced out going down. They do not radiate from the center.

Currants maybe? Look kind of similar and are edible.

Could it be this?
It's the Maple leaf viburnum and grows here!

 

[Retread]

Yum! Give 'em to someone special.
Nightshade?

Do we have choke cherries down here?

Different leaf pattern IIRC

My mom, RIP. used to put up a ton of choke cherry jam. Come to think of it, it was more of a shrub, small leaves.
