Crowley's Bestie, aka crush (Aziraphale) had recently planted some plants in the garden, but even tho Az was taking amazing care of them, they didn't wanna grown. It bothered Crowley to the core.

So, when aziraphale went inside to get something, Crowley went up to the plants and gave them a death glare. If looks could kill, the plants would die.

"Grow ~BETTER!~" Crowley says through gritted teeth. He clamed down as the plants got scared and grew a bit.
