As you can see…Kravitz doesn’t really have a green thumb
I imagine that after the whole thing with Shiro becoming a Paladin, Haggar would take some precautions about her prosthetics. Some kind of fail safe to make sure that her cyborgs won't use her inventions against the Garla. Some kind of controller? A bomb? The prosthetics running on Garla quintessence? Lance as the (former) Blue Paladin was a big hazard. I can't imagine Haggar or many Garla fully trusting him no matter his deeds.
