The old saying, "opposites attract" has a lot of evidence to support the truth of its claim. Some of this evidence could appear between two people, and at that, two counter terrorism operators.

Glaz was always of the opinion that his work should be done from a father distance. He did not think it necessary to close range when any decent marksman should be able to take care of an enemy from outside the objective. Glaz went even as far as to question the long range shooting skills of the other operators of Rainbow, though only in his mind.

Caveira was Glaz's complete opposite. She believed that the closer she was to her enemy, the better. She wanted to inflict pain in a personal manner. It gave her great joy hiss threats into the frightened ear of a terrorist fiend. Caveira found even more enjoyment in ending their life with the blade in her hand.

Though these two were quite different, there were a couple of things they shared. Glaz and Caveira both out lied on conversation with fellow squad mates. They would rather listen to what was being said and draw their own conclusions about the topic at hand. And thus, they both kept a mental dossier on each of their comrades. It was because of this that they had their first interaction.

One day, after a controversial mission debrief that involved all of rainbow, most of the rainbow operators headed to the wreck room to conduct their own "debrief" of the debriefing. Glaz was listening in on the conversation between GSG-9 and Spetznaz while Caviera did the same. Glaz was not very interested in the conversation at hand, rather he was interested to find that he had neglected to make any kind of observations about Caveira. He had never noticed her taking part in any discussion. He decided he would wait for her to join the one at hand. Little did the marksman currently realize that the woman was doing the same to him.

About 20 minutes later they had both caught on to each other. Waiting for the other to get involved in the flurry of words. This would be a problem as the sniper and the BOPE operator were both stubborn.

Glaz eventually gave in. however, he had a plan to put Caveira on the spot. He said, "I belive we are all missing a rather large problem of this new restriction... How will it affect BOPE" everyone was surprised to hear him speak but quickly turned their attention to his question. The debriefing had come after a failed mission. Because of this, the politicians had decided to limit the operational jurisdiction of rainbow. Brazil needed all the help they could get, but now rainbow couldn't interfere without government approval. With this single question, Glaz had turned all of the attention of the conversation onto Caveira.

Glaz watched and listened as his brilliant move unfolded. All eyes were on Caveira, as she was a member of BOPE. Her eyes widened, "I-I… I would prefer not to discuss this topic right now." And as quickly as Glaz had switched the attention of the conversation, Caveira had left the room. Glaz was now dumbfounded by the way in which, who was in his opinion, the calmest operator under fire had lost her cool. He had decided to leave the wreck room and on his way to his barracks ponder Caveira's reaction to his question. The marksman almost felt guilty. He probably shouldn't have been so blunt when he put her in the spotlight. Not to mention that in order for her to have a reaction like that, Caveira must have something on her mind that was deeply bothering her. He would have to make it up to her.
