Dylan Arnold, aka Theo on You, Has Fans Intrigued This Season

Though he's not very active on Instagram, Dylan does make time to pop up online every now and then to show his family some love, including his older brother Jordan. A few years back, he dedicated a special birthday post to him, writing, "Happy Birthday Bro!! Thanks for putting up with me all these years, and occasionally joining me in my high energy antics. Love you!"
