G-Man

A Mysterious Entity that intercepted in Richtofen and Geralt's match to steal the win, as if he knew he was going to win all along...

The Cryptical Bureaucrat
Mostly nothing is known about the G-Man, other that he is seen talking with people at intervals in the surrounding of those about to be contracted. He seems to appear in places of importance, and pay attention, lead, and somewhat "protect" those who appear to be any value to him or his employers, as during the Resonance Cascade incident, he followed Gordon Freeman and and Adrian Shepard around but ignore Barney Calhoun. In the former 2 cases, he "offered" an employment offer to those who appeared to surpass an incredible feat, and mention his employer's interest in them.

Season 3
The G-Man suddenly appears a third party to Richtofen's match and, surprisingly, fights himself as he appears as an incredibly strong fighter, which he probably hasn't done before in a long time as he merely serves as the contracter and not someone who is meant to interfere in previous events.

Now, The G-Man has appeared to have a deeper reason to be in TFR, and what might that be is the ultimate question.
