VIDEO Farrah Abraham revisits Derek Underwood’s grave in Season 4 promo

Tonight is the beginning of the end for the first mommies of Teen Mom. Catelynn, Maci, and Farrah have been out in full force hitting the promotional circuit as they and the network look to send the series out with a ratings boom.

In the latest promo video provided by MTV we see Farrah Abraham and Sophia visiting the grave of the late Derek Underwood, Sophia’s father, on his 21st birthday. No punches are being pulled here as we get an example of what should prove to be an extremely emotional 4th and final season as Teen Mom looks to sum up the incredible changes these young mothers have been through since their 16 & Pregnant episodes.

The following clip will be part of tonight’s two-episode premiere:

I think I got a little something in my eye. Hold on one second…

Here is what Farrah shared with Derek while their daughter played along the windy field as a vision of adorable innocence.

Well Derek I’m happy to see that your dad brought you some things for your birthday. I’m trying not to cry anymore about things because I do not want to be an unhappy person anymore. It’s really sad to me that I never saw you like get to do any of the things that you wanted to do when you grew up.

Now you’re 21 and I just feel like you died really early and you didn’t really get to experience life and it makes me really sad. Derek, I wish we could have gotten married and I wish we could’ve spent more time together but… And it just really hurts that I’m here by myself because I never wanted to be that person. But it’s okay that I am. It’s just what I have to deal with.

And I’m happy I don’t forget the things we’ve done together and I’m happy that I don’t forget that stuff.

Tonight’s premiere begins at 10EST.
