We know he’s from the mirror universe. We know he really hates non-Terrans (unless they are delicious perhaps). He cracks the invisibility cloak - and DOES NOT give it to Prime Starfleet before leaving. Why not? - he seemed to have plenty of time (and could warp away if need be) - he didn’t seem to need it to take out the Mirror Emperor - so why leave before it was in Starfleet’s hands? Certainly there was no easy way to know Discovery would return? - yes he needed the data from the 100+ jumps. Ok. He didn’t know there would be 100 jumps until 2 hours prior! So alternatively why not just have the ship jump for “calibration” or some other reason until he has his data? Ok I know - to confuse us. But from Lorca’s view - why not send the info?
