I don't know that they actually discussed why they couldn't destroy it. It took Vixen pounding on it with gorilla power to crack it originally, but we were never told why they couldn't blow it up or melt it acid or anything like that.

My handwave would be you need magic to destroy it (so Mari fit the bill in breaking it originally) but that still doesn't explain them piecing it back together and sticking it in a plastic case in the Bunker. (Other than maybe Ollie trying to emulate Batman and keeping souvenirs of his enemies in his lair.)

sticking it in a plastic case in the Bunker

At the very least, maybe a case that isn't transparent.

This is where is start my cheer of la-zy wri-ting ðŸ‘ðŸ‘ðŸ‘ðŸ‘ðŸ‘.

Should I ever need to hide away dangerous occult artifacts, I'm not storing them in museum-style display cases with pride of place. They're getting sewn inside sticky decades-old stuffed animals and put in a cardboard box on a closet shelf, underneath a pile of vacation photos and old Christmas cards.

Yeah, but now WE know where to find it.

Well, if it were me, I'd hide it in a box of tampons or something ... I've read that most men are very nervous about even touching the box.

Sleepy Hollow, did NOT just do that!

I've heard that that's a good way to smuggle drugs into Saudi Arabia.

Woah, The 100 is getting sooper creepy.

I LOVED that Clarke showed up just at the end. But omg what a nightmare that episode was. So many things going very very badly.

I still think Octavia's going to kill Pike, though he may well manage to get on Ontari's good side.

Wonder how the AI storyline is going to intercept with the Grounder issues. This is fascinating.

Argh, I'm so far behind!
