TUA Universe Theories: Former TFer Mack

This TUA Universe theory relates to Mack being a former TFer.

Theories.
Theory #1: What if Mack is a former TFer? Justin TFing and the Totodile TF Virus were his attempts for others to TF. The most plausible part of this theory is the fact that the head of Team A in Darmstadt's Story just so happens to be named Mack, and that story was obsessed with TFs!
