Andy watched how all three bolts hit Donny and assessed the situation almost instantly. The one hitting the head was a problem, the other two seemed to have missed any arteries, but their location was far from ideal, organs could very well have been punctured. This was on top of the earlier inflicted wound. With all the blood loss there was very slim chance to survive, even with treatment. And that was without taking any metal-forming properties of the bolts into account. Then there was the important safety rule in first aid which said one shouldn't bring themselves in harms way to help someone. With the pavise knight there who wanted to give them 'merciful deaths' he couldn't afford to keep his attention on someone who seemed doomed anyway. Right now he had to focus on the living and Kael was the only other living person in this realm who didn't want him dead. He had to help him. 

The thought process took mere second and Andy opened his backpack to get some of those spray cans to dissolve metal and put them in his pockets so he could easily reach them. Now that the pavise knight suddenly was an opponent it seemed like a good idea to keep them close. He looked towards Kael and the device and wondered how he could get there. He recalled he had moved before, but now that he thought of it, he wasn't sure how he had done so. Maybe he had managed to go where he wanted because he hadn't bothered himself with asking how to do it, he had just moved without thinking because he needed to be somewhere. Thinking he needed something to push off against hindered him. So he exhaled, focused on the goal and moved fast towards Kael. He made sure to keep an eye on the knight, one sign of that crossbow being aimed at him and he would get out of the way. As he moved he took one of the field triage kits from the backpack and hurled it at the pavise knight. It probably was one of the worst distractions he could come up with, but maybe it would help.
