Once they had arrived at their location Rēku was able to take in everything at once basically. So she'd turned to look around at the beautiful sites, then something had caught her eye. The black butterflies she knew all too well. Beautiful creatures, but that also meant something was going on if they were interrupting the mission. Then her one armed companion decided to converse with her. He really was a funny guy though. "Well," She started as she continued watching the butterflies approach as she lifted her left hand out for one of them to land on her finger. "it's pretty obvious isn't it?" She giggled softly as the butterfly landed on her hand.

After the message was recieved she closed her eyes as a smile grew further upon her face. Things were definitely getting interesting. "It's pretty simple to figure out, come on!" She said turning to him cheerfully. "Just look! Clearly the Soul Society wouldn't have sent a second team without telling me at least. On top of that if they were one of ours they wouldn't be casually out there like that. So, obviously the two probably already know each other! On top of that we know no other soul reapers should be in this area right now that was already in the world of the living! So clearly he's not one of ours. So tell me...What do you think after considering all of that? Plus the fact that you can feel his spiritual pressure?" Rēku had already figured out the possibilities. 

You had the first option of it being some rogue element, which in that case meant that the situation was even worse considering the rogue ex shinigami were mostly [i]those[/i] people. Another was that it was actually a hollow who had managed to obtain a true arrancar form, which in that case they would still feel more like a hollow. That brought them back to the first option. The real question would be how to deal with the situation. Then on top of that there were the head captains orders and the situation in the soul society. This wasn't exactly the best situation there could be. "Well in any event...We still need to do something despite who they might be, and then there's also the head captain's wishes..." She hated to sound more serious than usual all of a sudden and out of no where like this, but it was required of her. "So...We have a few options for this situation, Mr. third seat...Either we try and wrap this up quickly and head back, or you head back on your own since the head captain needs us to return and I will complete this mission on my own before returning. What do you think?" At this point she was testing him. She wanted to learn more about the man, and to challenge him. Of course he could take this in the complete wrong way seeing as she was so much younger than him, and was treating him almost like he had the intellect of a child.
