Advice on my scenario pt. 2

[sandi2]

As i have had to do all of my child swaps and whatnot through my mother in law, communications is a pain.

I just asked my mother in law to inquire about the denim jacket my son has that used to be long to my deceased brother when he was a toddler. My other brother and I both wore this coat as children, but it is mostly important because it was originally my dead brothers. Big sentimental value.

I KNOW AS A FACT that W has this jacket, as OM posted a photo of my son wearing it like 2 weeks ago.

I asked my MIL to let my wife know I'd like it back as id like to get photos of him in it for my mom before it doesnt fit him.

MIL's Response: "She said she thought you had it, she will look for it and send it over if she finds it"

Here's the rub: W doesn't know I can see things OM posts on IG, as OM has me blocked. I have a friend of a friend that sends stuff over that's relevant if OM Posts it (Note: I DID NOT ASK for this to occur, chalk it up to good intentioned friends trying to do right by me i guess)
So do I,

A.) Pretend i dont know about the photo that got posted of him wearing the coat in question and just hope she returns it?

B.) Politely tell MIL i know as a fact W has the coat and dont say specifically why, and that I dont appreciate being lied to?

C.) Send screenshot of the photo in question, thereby proving 100% that W has the coat and i know that she does, thereby blowing my cover with OM's IG page? (btw she lies to her mom a lot so MIL probably genuinely believes what she said to me about W looking for it)

Look, don't do this type of stuff. You are setting yourself up for a fall. It makes you appear unattractive and as if you have an ulterior motive.
