[He shifts some, folding his arms across his chest as he thinks this over.]
In this particular case, the rogue group felt the need to act on their own because the threat itself was familiar to them. It happened to one of their own and the situation itself was one that they've been forced to deal with during a long period of time in their own world. It's not strange that they felt a personal responsibility to deal with it without putting any outsiders in danger.
Now, I haven't been here long enough to really have a good idea of what the Defense Force was like prior to my arrival, but based on the observations I've made over the last few weeks... it's not surprising at all that this happened. Dissension is common even in the most structured of agencies, and our situation alone leaves us at a disadvantage - we all come from very different backgrounds with different experiences and training, and just with that we lose our sense of unity. Furthermore, the relative peace of Marina means that we can't build towards a sense of trust and co-dependancy, because we don't experience the stress required to forge those bonds. Add to that the fact that any single one of us could disappear without a moments notice and it's not strange that there's a lack of trust within the group.
