The "parents don't know but they will talk about it anyway" gag is not a new one, but it remains a sweet one when the parents do a good job (and aren't treated like idiots by exploitative kids). Like Karhall's mum here, who was asked to talk about Overwatch characters without knowing who the hell they were.

Karhall says (or at least claims that) she was asked "to give each character a codename she thought fit their appearance as well as some thoughts on what she thought their job was and who they are as characters."
I like some of these better than their actual character descriptions. Especially the Mercy one. For reference, the blue text is Karhall's mum, the green bits are him helping her out.
They're working their way through all 22 characters. If you want to follow along, you can here.
