What's up with Runner3's ending and ????? Island ?

[IAmSympathy]

So I just finished Runner3 recently and I noticed something that really disturbs me.

(Spoiler)
At some point on the final battle, the Timbletot stops attacking and looks like he's scared of something or maybe panicking.Do we have any explaination on that? Hidden lore? It really bugs me out.


Also what do we know about the Radio Tower Island? Has the secret been unveiled yet? I hear morse code from the tower and the satellite.
