SugarCube.State.variables.stormchild = undefined
SugarCube.State.variables.averytwin = undefined
(..because i'm simply amazing, i looked up the Dixon's girl code too)
There's also this below, so I wasn't entirely sure which was needed because it's been a while
/* EXTRA AVERY CHECKER */
<<if _averystop is true and $adisplay isnot 201>>
<<set $aback to -21>>
<<set $aback4 to 37>>
<<set $aage to 18>>
<<set $ran_beauty+=20>>
<<set $avalue+=6>>
<<set $adisplay to 106>>
<<set _lastname to "Dixon">>
<</if>>
Edit: Oh duh, 201 is stormchlid. *facepalm*
Edit 2 for if curious; code for -21:
<<if $aback is -21>>Alright. Silence! This cute little thing here comes from an uppity family in Whitehaven. Her dad got purged after siding with Miss Aria Bianchi and his entire family ended up on the market. We just sold one of Mr. Dixon's daughters to Dockgrave. I bet $aname here is the lucky one (laughter)!<</if>>
