Back in December, Kailyn Lowry sent Jenelle Evans a sample from her new line of hair care products.
And Jenelle proceeded to light the gift on fire.
That incident was featured on Monday night's episode of Teen Mom 2, which means we finally got some insight into what the hell was going through Jenelle's head.
Unfortunately, Ms. Evans is pretty clueless herself in that respect.
As far as we can tell, she just really likes fire and really, really hates Kail.
Take a look:
Okay, maybe not "besties," but these two used to be pretty close friends. Those days are long gone now.
Point of No Return
Kail and Jenelle are well past the point where they might have salvaged their relationship -- but that hasn't stopped Kail from trying.
Back in December, Kail launched her Pothead hair care line, and she sent free samples to everyone on the Teen Mom 2 cast including Jenelle.
On Monday night's episode, we got to see how the incident played out -- and it was every bit as bonkers as you would imagine.
Before she even sent the package, Kail speculated that Jenelle might use it as "target practice." She was almost right ...
Jenelle not only lit Kail's gift on fire (and almost blew herself up in the process), she made a video of the incident and posted it to Instagram.
