I think that Daniel's closing line was fishy:
That stuck out to me for some reason.He's no more a part of the Order than I am
I think Bree's lost her damn mind because of everything she's been through and I really think that, after seeing Jonas, he's being sincere about not knowing why the symbol was there, what it was, or if his parents were even involved in the Order. He seems extremely distressed by the turn of events.
I really think that it's extremely effed up of Bree to do this after everything Jonas has done for them. If I were Jonas, once they untied me, I'd tell them to take a hike.
