The sentence I am trying to assemble is this:
Wait, first some background. I needed someone to help me accomplish something but I could not reach them. They were not where they were supposed to be. So the question in English is: "I wonder what else the could be doing."
I got this far:
Me pregunto qué otras cosas . . . .
Now, I am pretty sure that I came across a more appropriate verb for wonder or "I wonder" but I've also heard many people use preguntar for such purposes so fine.
Now, "they could be doing"
The first issue is "could be doing." Part of me wants to use the conditional form of hacer. However, (I know you aren't supposed to start a sentence with however but let that slide for now), the real problem is that I pretty sure that this clause needs to be in the subjunctive and there is no conditional subjunctive as far as I am aware. So I move on to something like "pueden haciendo" ending up with:
Me pregunto que otras cosas pueden haciendo.
First, help with with the notion of "I wonder" in the context of I wonder what is going on over there.
Second, help me with the second clause. Is it, in fact, properly subjunctive and, second, what is the proper form of the appropriate verb, verbs, gerund or present participle.
Thank you so much in advance.
