You think like I do.
If the Oresians are being hunted by the Klaxians then we should try to form some kind of alliance.
What if the Flower ships are Oresians letting us know they're here, personally I think that if the Flowers were Klaxians they wouldn't just scan our ships, they'd blow us to smithereens at first sight.
At E3 it was already mentioned that they know more about us than we about them, so Klaxians would've known already how to destroy us.
Oresians might use the hyperdictions as a way of introduction and that they mean us no harm.
That would about a good of way of doing as a police officer pulling you over via a pit maneuver then shining an annoying flashlight (or torch as people like to call it elsewhere) and honking their horn at us then randomly leaving with out communicating.
I'm pretty sure that that particular behavior has more to.do with them looking for something instead of communication. The unknown artifacts, probes, and links ECT would be a much better way to try and communicate with us as they could leave it for us to find, learn about what they intend with out the risk of leading to conflict.
