That… actually gave Handy pause for thought. He pondered for a minute. If she was serious, he could ask for some boon or benefit to Gethrenia, a nice little 'sorry for disappearing for months on end' present to Joachim and everyone back at Skymount. However, that wouldn't be anything truly meaningful in terms of making him trust her. What did she care for material loss if it meant she had all of his secrets, never mind whatever she could do with those secrets? He could ask for Stellar's head on a plate, and as tempting as that would be, he knew he could not ask for that. Celestia if nothing else, was fiercely protective of her citizens based on the barely concealed fury behind her eyes when the earlier arguments touched upon the deaths of Manehatten. He didn't have enough leverage for that favour. Then, on a whim, he thought of it, something she could give him, here and now, that would bind her to give him the guarantees he needed.
