If you were in stealth, then there's a good chance you hid from the cutscene.
I wish I was joking...
Currently, if you sneak, you can bypass a great many cutscenes and event triggers that should play (for example, if you sneak past the sigil near the crash sight, gale does not appear from it); if your whole party was in stealth and standing well back, then there's a possibility that the cutscene failed to initiate for you because you were hiding from it.
There are a number of oddities and bugs with that sequence, though you may have found another new one ^.^
