Honestly this show is just so f**king dumb that there seems to be a threshold where you can excuse a lot of stuff until you just cannot anymore, and then everything is stupid.
For me 3x12 is probably one of the worst episodes in Discovery, if not the worst, when it comes to the sheer amount of incredibly stupid shit.
First you have the whole concept of the phaser made out of programmable matter that just sits in your sleeve until you need it. I actually thought it was the anti-tracking device given to Saint Mary Spock by Book after they crash landed his ship in the hangar. But then I had to watch the accompanying episode of The Ready Room to find out nope, it's new 32nd century gear they were outfitted with which was never explained in show. Then I quickly scanned through the entire series and found that none of the crew ever wore it after the upgrade, but it suddenly appears on Saint Mary when needed. The ONLY character wearing it consistently throughout the season was Lt. Willa from 32nd century Starfleet.
So she has the magic space dildo phaser, but then decides to kung fu the Emerald Chain guy that's just f**king about for no reason. Coulda stunned him, coulda Vulcan nerve pinched him, but nope, when she has the tactical advantage of being hidden, her enemy distracted, and the complete element of surprise she decides to announce herself and slide in for a kung fu fight, ultimately getting stabbed in the leg.
Then, she leaves the guy unconscious in the middle of the walkway where anyone could trip over him, and then takes his commbadge equivalent. So as soon as someone finds the body - which is pretty much straight away - and notices the commbadge missing, well, all they need to do is scan the ship to find out where the it is. Ok...
Then we're using the magic space dildo phaser to cauterize a wound. Presumably the programmable nature of the programmable matter behind the magic space dildo phaser allows the wrist device to become any number of useful tools like a medical device, but ok, we'll accept that it can only be turned into a phaser for the moment. Fine.
She uses the magic space dildo phaser to blow up some shit in the Jefferies tube to set off the fire suppression system, the amazing response of which is just... whoosh! Everything and everyone gets flushed into space. Incredible! Why would anyone go into a Jefferies tube to fix anything when a small fire is just going to result in.... whoosh! Seeya later! Can you imagine that?
"O'Brien, get into the Jefferies tube and fix up the electical fault!"
"Are you shitting me? Have you seen how occupational health and safety unfriendly our fire suppression system is?"
I'm certain that the fire suppression system has been covered in previous episode of TNG, etc. before and involved using shields to put out flames. But here, there wasn't even really an out of control fire or anything? She just blew up a small dome thing or something?
Then we have the weirdo looking Emerald Chain lady coming at Saint Mary in the Jefferies tubes. Other people are shown making their way through the tubes with guns drawn. Not this lady! And somehow she sneaks up on Saint Mary - WHO HAS THE MAGIC SPACE DILDO PHASER IN HER f**kING HAND - and is able to grab onto her legs. Oh, but don't bother using the phase that's IN YOUR f**kING HAND to swat her away, just let her hold onto until your boots come off and your little strap breaks so you almost end up in space with her.
And that's just a few minutes of Saint Mary's Die Hard sequence. The entire f**king episode is full of shit like this, not to mention the episode prior where the Emerald Chain boarding team all just beam through the f**king shields... Books ship gets into the hangar because shields went down momentarily... for SOME REASON... The transwarp tunnels that are just f**king everywhere, first allowing Osyraa to just venture over to the nebula, and then allowing Book's ship to get back to Federation HQ seemingly in the same amount of time it too Discovery to jump there.
They set up "the burn" but then at every opportunity they undermined it. It caused all dilithium to go inert galaxy wide, but wait, not ALL ALL dilithium. There's transwarp tunnels f**king everywhere. And then just as easily as "the burn" was caused by a Kelpian mutant manchild, BAM!, it's solved, because when you find the cause of the "the burn" you also find an entire planet made out of dilithium!
God, don't even get me started on Adira and Gray, or the fact that all the alphabet people on this show have been segregated into one place. I don't even know who is in what role now. Who the f**k is the Chief of Security? Who the f**k is the Chief of Engineering?
What a f**kin' joke this show is. The CW makes better shows than this shit.
