The Mouse, ejected Pulsar black hole out of Sagittarius its Super Nova. with Parallel Filaments of former young Herbig Haro systems.

According to Q-FFF theory, the Milky way central Black hole seem to attract but also repel, the so called Tadpole black holes , being central BH remnants of Super Nova called runaway black holes, like the Mouse Tadpole also seem to be.
Tadpole black holes are single black holes like single ball lightnings driven by the self produced plasma tail , away from the local center of gravity like the Sagittarius BH. 

(see: Q-FFF theory.)
