I think hes trying to find out if she loves him he doesnt want to come right out and ask so he careful in asking her questions

come on, dudes ((or, dudette(s), however it may apply)), of course he knows...i mean, given his respectful "smugness" when asking her why she came back....but then again, when he asks "only the children"...or "you are"...well, my logic breaks up. ok, so maybe he didn't exactly know. or whatever...ok, i am wrong, i will deal with it.

No way, he knew. The way they looked at one another and Maria got caught blushing after they danced at the party. He knew. I bet even Brigitta knew. I just wish they would have filmed a scene where they asked the children permission to marry.
