Aldnoah Zero - ep04

Now that the battle with Trillram is over they are trying to regroup with the rest of their forces. That it is in this moment of peace that some of the unresolved issues are being addressed. That the first of the issues is the Princess of Mars introducing herself as Seylum in-front of Inaho and his sister Yuki. This leads to his sister getting the wrong idea on why Seylum wants to be alone with Inaho. This leads to her revealing her identity to Inaho which wasn't unexpected given her supposed hypothetical situation. This causes Inaho to keep her secret because she would be the ideal target to take out their grief on. Although this also cause a problem with how she will tell her people that she is still alive, so that the war can be stopped because all long range communication are impossible.

This also hits on another issue the fact that Slaine knows that she is alive. Initial he wanted to tell Count Cruhteo, but with how he is acting Cruhteo might just kill her anyways because it would be inconvenient if she was still alive. That with her death they have a valid reason to wage war on the earth so that they can take for themselves. That until Slaine can really find out who is really behind the assassination it is best that the Martian continue to believe that she is dead. This leads to him convince the count to let him join the fight because the is the only way his is going to discover the truth.

This returns us to Inaho and the others as they are gathering supplies while waiting to rejoin the rest of their forces which are set to converge on this abandon warehouse. That while waiting they are attack by another enemy, but instead of trying to defeat them Inaho's goal is to buy enough time so that they can escape. Also his other goal is to find out the characteristic of this new enemy. This leads to him learning that explosive round are useless because the enemies sword just cause them to explode while armor piercing rounds are diverted because the tips of the bullets melt which cause the bullets trajectories to be altered. That through the fight they just didn't manage to gather intelligence on this new enemy but they were also able to do enough damage that would prevent them from following once they began to make their escape. The question is what will happen now that they have rejoin with the main force.
