She's going to stop using her power for a minute and maneuver onto her partner's lap, given the weather this doesn't immediately increase skin contact much but it does open up new options, as well as provide the possibility for more restraint if this turns out to be really bad. She waits to be at zero again (it doesn't take too terribly long, a thin slice at max range was building backlash but not very fast) and then reaches out with her thin slice (she still remembers where it was pointing so it's not hard to find the helper). It occurs to her that ideally the helper won't end up touching her, considering that even at low levels her backlash doesn't like that, and the helper is not a compatible esper to even partially counterbalance that so she tries to focus on a space a couple of feet away from her as she 'grabs' and 'pulls' on the sense of the helper's location.
It works. The helper appears in the space she thought about. She stumbles slightly as she appears since the ground is slightly differently uneven than where she was. The two of them appear for a split second to be linked with a thin cable of blueish light. She immediately drops her power.
The backlash is more than she's had so far and she flinches slightly, but is able to force herself to remain still and remember that she needs to keep touching this person. She's not sure she'd be able to force herself to keep touching somebody who wasn't a compatible esper at this level though. Probably this is not the time to test that. In case she reflexively punches the woman or something.
Since they seem to be done for right now, the helper opens the door to the car parked nearby and she is placed on the back seat and scoots across it to sit by the opposite window without breaking skin contact with her partner after which her partner slides in after her and the helper slides in next to them on the other side of the car. This way she has only one person physically pressed up against her. It's still uncomfortable. Once they're in the car and isolated from cold and judgemental people, sleeves can be rolled up as far as possible. One of Annete's sleeves is rolled up slowly, to gradually increase the skin contact the other fast. The latter turns out to be worse and she flinches again.
And then drive off back to the city.
