An interesting reflection on the implied verb

As noted below, I think you can use "from" with the verb, but not with "expectations". Also, in your example "What do you expect to get out of this encounter?" the prepositions (or compound preposition) "out of" modifies "to get", not "expect". Thinking about this, it could be that there is an unspoken subordinate verb: "What do you expect (to have/get/receive) from this encounter?"

I cannot conceive of any scenario where 'on' would be the correct preposition to use with 'expectations' (other than a purely fortuitous collocation, of course!)

The whole idea of 'expectation' is that it is from or out of something — why, even the Latin prefix ex- suggests that!

If you used the verb 'to expect', it may be easier to see the right choice of preposition:

What do you expect to get out of this encounter?
I expect better behaviour than that from you.
What does she expect of me?
What should we expect for next year's theme?
