Helicity is a topological invariant in ideal fluid dynamics, reflecting the knottedness of vortex structures. An important manifestation of helicity conservation is the natural tendency of vortex tubes to become anti-parallel during reconnection. Deviations from this anti-parallel configuration during reconnection are directly linked to helicity dissipation. In this talk, I will present a geometric framework for systematically perturbing vortex initial condition in a way that necessarily disrupts anti-parallel alignment during reconnection. Central to this approach is probing reconnection events in which the reconnecting points on the vortex lines undergo a bifurcation.
