It's always a good idea to lock your post from Hostiles sweetie, you never know what they can get from an open signal...plus they can respond to your post as well and some of the more clever ones can lie and pretend they aren't hostile at all.

We have to be careful.

The Digimon may have been acting upon your burning hate for the tamer...it's really hard to tell having not been there. And it was your first evolution I'm guessing.

All we can do is wait for the next one...maybe try sparring with someone and getting him to evolve again.
