While hanging out in Thomasville, GA, a mere 18 minutes away from his hometown of Cairo, GA, Isaac shared he caught up with his sister Moriah Plath, who was in town visiting. The pictures of Moriah and her younger brother Isaac were mostly sweet, but some viewers disapproved, posting angry emoji covering up Isaac's middle finger. Welcome to Plathville fans immediately called the young pilot out for making such an immature gesture. In now-deleted comments, Isaac fired back at his haters, writing that he wasn't letting the "world corrupt" him. Followers also started questioning his religious beliefs, but once again, Isaac made sure to set followers straight. He said, "you can't tell how my relationship with God is from one post."

It seems like Isaac was trying to look like a cool 16-year-old. The blonde reality star sported a baseball cap, khaki shorts, and a blue polo top. So, while he may have been pretending to be a bit wild, he still looks extremely young, with a lot to learn. This isn't the first time that he's hung out with Moriah since she left home. Some fans can't help but wonder if her independent lifestyle, with no rules, is starting to rub off on the impressionable teen.

Despite posing for questionable photos, the Welcome to Plathville star is still planning to get his pilot's license soon, so he can work for a cargo company. With the troubles at home, Isaac has made sure to step up, by helping his younger sisters to navigate the tough times ahead. Fans hope he doesn't teach the little girls any of his graphic poses, as some could take offense.
