Duct tape
The other splint
Short answer
It repairs, it restrains, it is always worth a slot until it isn't.
Also: tape
How it works
Tape is the generalist repair. Also a restraint. Community jokes write the rest.
What to do
Keep a roll. Levi will find a use.
Don't
Don't tape Kane's mouth as a bit on a live overlay without consent — that's a different show.
