  A key issue in tropical geometry is the lifting of intersection points to a
non-Archimedean field. Here, we ask: Where can classical intersection points of
planar curves tropicalize to? An answer should have two parts: first,
identifying constraints on the images of classical intersections, and, second,
showing that all tropical configurations satisfying these constraints can be
achieved. This paper provides the first part: images of intersection points
must be linearly equivalent to the stable tropical intersection by a suitable
rational function. Several examples provide evidence for the conjecture that
our constraints may suffice for part two.
