Perhaps this just restates the problem, but maybe it's
easier to look at the situation as multiple events.

You have the player giving the item to the mobile, which
causes two things to happen.  First, the mobile examines the
object.  Second, a new event is created/registered to occur
at some point in time in the future.  Namely, the mobile
gives the object back to the player (and this has its own
set of criteria to meet).  So, I guess the question is, how
are you dealing with a situation where one event causes
another event to occur after some delay in time?  Or have I
simple restated the question?
