Something else I noticed, though it had little to do with the partnership:
Angela told Reibmann about the "old gold mine" but pointed out to everyone that it had not yielded very much gold even when it was in operation. We saw Reibmann and his lackey find the treasure in the mine shaft, but he never mentioned the real reason for his interest to hostages Angela, Julia, etc. Richard went after them in the mine but it collapsed before he could go deep enough to see what was in the 'secret chamber'--he escaped while they didn't (or at least we're led to believe this).
So my question is: did the rest of the characters never even learn that a massive hoard of looted Nazi treasures was buried on the property?
