I've seen a couple of posts now about people's suspicion over The Capitol being able to find a girl that could replace Louella as fast as they did, especially after finding out Lou Lou's from District 11
But I'm gonna be honest, when I found out she was from District 11, it actually put a lot of the pieces together for me. My mind immediately went to Seeder, the D11 female victor in Catching Fire
If its been a second since you've read CF here's her description:
She looks like she could be from the seam. I wouldn't be surprised if Seeder's description is the reason SC chose D11 for Lou Lou tbh.
Also for making their faces match, I've always just kinda assumed fast fashion cosmetic surgery is common place for The Capitol so there's probably plenty of surgeons able to do the job quickly and well enough to pass her off as Louella to anyone who didn't know her.
And it’s not like they did a particularly clean job at it either. Their “solution” was so incredibly slapped together and messy (And that’s HORRIFIC because we’re talking about a CHILD). She’s hooked up to drugs 24/7, which could easily be ripped out, manipulated, etc. and also make her barely able to function and causes more problems for the Capitol than not. One thing that’s brought up over and over in sotr is the Capitol’s gross incompetence, but because of they’re good at propaganda, you wouldn’t realize it. Lou Lou’s another example of that
(Also....Seeder's in her 60s in CF...meaning she would have been a victor and, I dunno, old enough to have a 13 year old by the 50th Hunger Games...I'M NOT SAYING SHE'S LOU LOU'S MOM I'm just saying the timeline lines up weirdly well)
