For Mari, it's very possible! At least she didn't come across a similar incident like pouring milk into a bowl of cereal and have it burst into flames!
Anyways, episode 3 got really interesting as we got more insight on the aliens (yes there are aliens involved)! [spoiler]- Hehehe, so Hagino is really an alien, and she's the commander of the spaceship Blue.
- And just to note,
ALL of the aliens are female with blue eyes and white hair (well maybe except for Hagino because she has to blend in with the humans) which means.......
-.......they introduce 2 lovers on another ship where one alien named Azanael was thinking about her lover Onomil. SO CUTE!!!
- Though I think something tragic happened to Onomil that may have been related to the incident 5 years ago. Awwww....

Back on the human side, well.....[spoiler]....Mari couldn't sleep well last night ever since that little incident where she saw Hagino talking to the alien Tsubael. So she pretty much stared Hagino down and the same with Hagino. Of course this led for Mari to fall asleep.[/spoiler]
Hmmm, this is slowly building up pretty nicely. If this keeps up, this could be
it!
