  We discuss several issues related to recent work on high energy evolution. In
particular we show that the Hilbert space for action of the operator of the
evolution can be conveniently defined by the space of weight functional
introduced recently in \cite{kl4}. These weight functionals automatically
implement the correct properties of the charge density correlators, thus
eliminating the need in explicit introduction of the Wess Zumino term. We also
discuss various aspects of Dense Dilute Duality in the toy dipole model.
