No, we were already working with the Scions at that point.
We'd been on their radar since the Lv5 quest where, variably for
each city quest, we get attacked by something-or-other and the local Scion comes to our rescue, and we have our first vision of Hydaelyn. We describe it to them, and (while it isn't explained at this point) they realise we must have the Echo.
Then we get officially recruited to the Scions at
Lv17 after clearing the first three dungeons and then coming to the rescue of a woman being bullied by some thugs, at which point the Scion we'd previously dealt with comes up to us and invites us to join their secret society. Investigating Ifrit is our first assignment with them.
