Spoiler for full ep4:

1) Since we are most likely driven by "Witch's side" explanations during the narration, it wouldn't be that weird. Remember that the "continuity" has been hinted ever since episode 2, and clearly mentioned in Ep3 by Ronove.

2) I really doubt you have that much possibility to land on helicopter on an island like Rokkenjima

3) No, Virgilia isn't human. And Remember that Beatrice is "dead" because her body, her essential vessel was lost years ago.

4) Not enough clue to figure what is Battler's sin.

5) Battler was shown "borrowing" the right of using red, as Beatrice allowed him to use it. Therefore, it is very unlikely he could start trying to blurt random guess to find out what really happened.

6) Kinzo's confirmed death just leave too much things to be settled.

As chrono explained for Virgilia's fun comment, it isn't anything surprising: heck, even Ange and the rest talked about "Episode 1" incident etc. The term "episode" is also used instead of "game", and that happened already in ep3.

Last point: a huge mistake from our part. It is supposed to be "sumadera kasumi" obviously.
