  Ionel's GW invariants relative normal-crossing divisors appear different from
Gromov-Witten invariants defined using log schemes or exploded manifolds.
Appearances are, in this case, deceiving. I sketch the relationship between
Ionel's invariants and their exploded cousins using the example of the moduli
space of lines in the complex projective plane relative two coordinate lines.
Even in this simplest of examples, 13 different types of curves appear in
Ionel's compactified moduli space, but these different types of curves can be
understood in a unified and intuitive fashion using tropical curves.
