This mission's been a long one, by the measure of her career so far. The most she's stretched herself - of course, new technology helps. Jack's a surly coworker, especially stripped of his supervillain grandeur, but the man knows his way around the technological marvels of the new age.
Like pain rays. Which, given Zenith's power source, and that the vacuum of space can only ramp her up so far, has proven astonishingly useful - enough she's been bopping around a slice of the theoretical inner Oort cloud, dropping off space probes and taking a prodigious number of readings. She doesn't need any kind of provisions to keep running, so she's basically just continuing until she gets bored or until the 'please come back by this time' clock runs down.
Given she's got a library with thousands of books loaded to pull up on her HUD, boredom's probably not the problem so much as loneliness, and... Zenith's been getting used to the dark, out here. It's cozy.
Still, she's never done out of contact missions for longer than a week total before - never needed to - and it took her two to get this far in the first place. She'd... Like to see another human, she thinks, stowing the last of her sensors. Another face sounds nice.
She ramps up Jack's newest gizmo and begins the long trek back, one astonishingly far range teleport at a time. Zenith has no idea how she's managing it mentally, really - even with aim being only a fuzzy concept, astronomical units are huge.
She actually needs to start thinking about aim some as she passes the outer planets. Getting into Earth's atmosphere normally takes an exhausting number of increasingly short range teleports to refine where she's going, until she has a good sight of the ground. (She's teleported into the ground more than once; luckily, the same side power that lets her teleport around the vacuum of space in her pajamas (not on official missions, of course, but, well, when she's off the clock...) makes it technically impossible for her to telefrag in a way that hurts her.)
She thumbs the button to dial down Jack's gizmo's output once she gets close enough Earth's bigger than a dust mote. For all it's sometimes disorienting, ramping her power down helps her aim without an error margin measured in millions of kilometers -
Zenith proceeds to learn a very, very valuable lesson about trusting mad scientists' gizmos. Of course, it'll take her a while to get back to cuss him out -
Given she vanishes from the void as she reorients toward Earth...
And doesn't reappear in her own solar system.
