When the person on the other end of the scroll started replying with the coordinates, Setsuna sighed partly in relief, then jumped when an unheard Calen started speaking to him. Instinctively he covered the scroll, but as Calen expressed his thoughts his grip lessened further and further as Setsuna got more distressed and conflicted. Thankfully Anna threw in her own look on things; that eased things in his mind a tiny bit.
Calen's words rang true: to even reach the survivors required traversing pitch-black rooms with Dust knows what inside, in addition to bringing Taro with them, only slowing them down. In addition, both he and Calen were in bad shape, ignoring the elephant in the room which was, again, Taro. But how could he vent his own thoughts without possibly sounding selfish? There were people down there in need of help! He couldn't possibly just leave them and still call himself a Huntsman. And yet he couldn't just order them to aid him in such a suicidal mission...
"Anna. Calen. While I might be your team leader, there is no way I will order you to follow what I am doing. Take Taro and whatever you managed to salvage from that building and get out of here. Return to Beacon and request support. As for me...you know my decision. It doesn't matter to me if I get injured. What does matter is getting innocents out alive." He thumbed several buttons on his scroll, which had shut off, and returned it to his pocket. "Of course, you are free to help me, and if you do, know that this is much more dangerous than what we faced before. But also know that you have my eternal gratitude. If you do leave, all I ask is that you return with help." A rocket locker, trailing fire, zoomed across the sky and slammed down somewhere behind him. The front of the locker had the words "Full Saber Kit" marked on it. Opening the locker and attaching the equipment onto his backpack, he returned to the group.
