Ruby kept her expression and she grin bit wider to see Mira struggle now with Jareth who seems just warming up! Jareth is smiling and he replies back to Mira; "Oh? You know I got<em>lots</em>of replacement batteries, ready to replace worn one when I am low in power. So in that sense battery is better than slow and steady going fusion engine which cannot be replaced and need wait long while until it's fully charged..." Jareth did not touch her but he kept his face close and so his grey blue eyes, also using his german accented english at it's best. As accent is naturally huskier volume than normal speech.
