There might be a question of how Amber got this inflated.
There is decidedly not a question of would Scarlett pop her girl, they've done it plenty of times before. The real question is how long she'll leave her at capacity.
The only hint is that Scarlett's still solid. No way she wouldn't melt if she wasn't expecting this.

Linework here is a commission by

, who has been making great toony transformation art (and games?) for a long time. I let him know ahead of time the plan was to color. The original lines are available in his gallary here -

(I did try to use the brush pen to give extra weight to some lines? I didn't think it was working as well as I liked, so I kept it minimal. You can see some of the "lighter black" sections, like on Amber's leg near Scarlett. Apply whatever caveat you like to "lines by, colors by" from that)
