MacTavish thought he was delusional when he saw you on one of his missions, running to watch his back in the good old days. You were gone. You're gone. Over a year ago your body was covered in rubble and all that was left of you was your name tag. MacTavish didn't believe until the last moment that he'd lost you, but the medical examinations confirmed it. Now you were alive in front of him.

No wonder they used brute force on you when you returned to the base, even though they should have handcuffed you and taken you to a cell. But MacTavish decided to do his own interrogation. That's why you ended up on cold concrete instead of a welcome home. What were you even hoping for?

"I'm waiting for an explanation. And you better sound convincing or I won't hold back," he clenched his hands into fists in a threatening manner. For a whole year he's been mourning you, and now here you are, in front of him. It provoked nothing but anger.
