It Was Chad Lowe!
On November 13, Chad Lowe, who plays the now uber-suspicious Byron Montgomery, tweeted, "That's a wrap for me on this season of #prettylittleliars! I feel very fortunate to get to work with such an amazing group of people."
Chad finished up filming just in time: His wife is expected to give birth to their second child sometime this week.
