On Monday night's season finale, Ryan Edwards delivered what may be the most shocking moment in Teen Mom history.

And we're not even talking about his truly bizarre parking lot wedding to Mackenzie Standifer (above).

No, we're talking about the scene that took place earlier, during Ryan and Mackenzie's drive to the wedding ceremony.

The now-infamous one in which Maci Bookout's former boyfriend was straight up nodding off behind the wheel.

We saw Ryan cruising along a highway with Mackenzie sitting on the passenger's side in her big wedding dress.

His eyes began to close, and when she asked him about it, he said that it was hard for him to see with glare from the sun.

But then he started swerving, his head fell back, and she had to grab the steering wheel to prevent him from crashing.

That would have been horrifying enough, of course, but Mackenzie's reaction made the whole thing even worse.

She certainly didn't call off the wedding after he put their lives in danger, but beyond that, Standifer didn't seem particularly alarmed.

Mackenzie didn't appear afraid, or even uncomfortable enough that she suggested Edwards pull over so she could drive.

No, instead of doing something reasonable, she just looked annoyed and hit him when he started nodding off too much.

She also turned off the cameras, because their image is more important than their lives and those of the people around them.

But even though she turned off the cameras, she left their microphones on, so we got to hear her ask him if he's taken Xanax again.

Then, of course, when they managed to make it to the wedding in one piece, Standifer was beaming while Ryan's mother was sobbing.

During the wedding itself, Ryan still looked like he was nodding off ... if you look closely, you can see his eyes are closed at times (above).

But today we're going to focus on that terrifying pre-wedding drive ... and how notorious Teen Mom troll Simon Saran is weighing in.

Simon, who occasionally dates Farrah Abraham when he's not stirring s--t up on Twitter, claims an MTV producer supplied Ryan with drugs.

Yes, Saran says this happened right before that drive.

"Someone needs to open up an investigation on Kiki giving Ryan pills," Simon tweeted yesterday, calling out one producer by name.

"It's really f--ked up! They could have died or killed!"

He's referring to producer Kiki Malone, and this isn't the first time he's accused of her of having something to do with Ryan's drug use.

Earlier this month, he asked his Twitter followers if he should talk about Kiki "giving Ryan pills during shoots or save that for another day."

This time around, someone responded to his startling accusations, telling him that he didn't actually care about Ryan Edwards' welfare.

Rather, he just wanted to distract everyone from how awful Farrah is (not a terrible theory, but we'd say he's merely an Internet troll.)

Simon insists that he does care, though. Why?

"I had a close friend die from an idiot under the influence crashing into them as they were talking on the sidewalk," Saran responded.

As much of a jackass as Simon usually is about everyone on Teen Mom, it seems like he does genuinely care about certain aspects.

Recently, he also urged Amber Portwood to come forward if she is truly a victim of domestic abuse, as she strongly hinted.

He loves attention, no doubt, and knows he's going to get it throwing around such accusations. But that doesn't mean he doesn't care.

Noble as his intentions might be (emphasis on might) we don't know if he's telling the truth about where Ryan Edwards gets his drugs.

Furthermore, even if he is telling the truth (emphasis on even if), we have no idea how Simon Saran obtained this info in the first place.

Simon does have a point, in any case:

It would be interesting to know how much MTV knew about his drug use, and when, prior to that insanely dangerous scene that aired Monday.
