No need to keep reading cuz I'm about to end Igarashi's whole career
Well, the second part of the title is just an exaggeration ofc, but..
Look carefully at this panel, it's telling the whole thing if what I think is correct.
While we saw lots of hints about Rikka being Apollo, this came too and emphasized my doubts, that the one he was talking with is Rikka (the transceiver). Also, Shinobu's wearing the ring is perhaps a foreshadowing about her being the future wife, and above all, there is the "prize" term, it also supports this theory (even tho, Idk what these numbers mean).
So in summary, it is very likely that Apollo not the endgame after all.
