As from what they are talking: They worked together once when they were mercenaries. Nothing more is said there. Asami even had to think what the other one's name was and the other was suprised Asami remembered.

Good catch! I am sold to your theory. What are the chances YA just made those two ties look exactly the same without even noticing? Just no way! I just hope he is not doing that because he also fell for Asami and he did not reciprocate his feelings xD We don't need a second Sudou. But this new dude must be doing it for the power or some kind of revenge we don't know about yet. We're finally gonna dive into Asami's past.
SPOILERS!

I claimed tanned, blonde guy is the new bad guy:
Once you see the raws or uploads compare the tie of the guy leading the attack on the hospital with the gas mask on to the one of Alec (the blond guy Asami meets at his brother's place) ;)
