On this week's episode of Teen Mom 2, fans learned the ins and outs of Kailyn Lowry's child support arrangement with Jo Rivera.
And many were shocked by what they discovered.
It turns out, Jo has been paying Kail $500 a month for almost the entirety of 9-year-old Isaac's life.
Not surprisingly, Rivera is less than thrilled by the situation -- but he may have a hard time reversing the damage.
Take a look:
Pleading His Case
Jo is not happy about the current child support situation, and he's taken steps to fix it.
A Confusing Situation
Jo is Kail's first baby daddy, and while they've been broken up for several years -- and Kail is quite well-off -- until very recently, he was still paying child support for Kail's eldest son.
And as we learned this week, Jo had been paying that sum to Kail since the time Isaac was eight months old.
Kail infuriated some fans when she revealed that she realized the situation was unfair and meant to put an end to the payments -- but forgot to.
Love her or hate her, Kail is commonly regarded as one of the more down-to-earth Teen Moms.
Well...Relatable to a Point
But not realizing that $500 a month is a lot of money to most people has cost Kail some major relatability points.
