Even if Tarn was crazy and insane, he would do anything for you. He would slaughter hundreds for you if you gave the order. It was just his way of showing affection.

As Tarn walked with you throughout the ship, escorting you to the Medbay because of some re-opened battle scars, he made sure that no one touched you.

He took you to Nickel, and as she took care of your wounds, Tarn was worried sick the entire time. He kept assuring you, who frankly didn’t care, that everything was going to be okay.
