Adrien will mostly have been listening to everybody and leaning towards the Talk it Out but upon learning this information from Tony as well as some ship specs (thank you roomie!) Adrien would propose:

They put a genuine attempt into Talking it Out with hope to sway the Caducians into a peaceful resolution.

This is also time to be utilized by Team Offense and Team Defense to develop and position themselves in case no peaceful resolution can be found.

If/When the Caducians refuse all reasonable efforts and/or start hostile actions, the Moira (regretfully) finishes it. Leave no survivors.

You don't leave an enemy still standing at your back. The Moira doesn't seem to need enemies stalking us through space. :(

Also if the "Send a negotiations te3am to the Caducian ship" is the way the group goes, Adrien will support Elizabeth's idea of also utilizing that group to lay down some sabotage/attacks form within, WHEN things go pearshaped. He would also advise that the group be made up of volunteers who understand that they'll have to leave behind their weapons as a show of good faith but then be on their own for extraction and won't be a priority for the Defense or Offense group.

So basically negotiation team better have good plans C, D, E and F.

And then he'll volunteer for the team.

ETA: He would be vehemently against using Bruce in any capacity that involves handing him over.
