What happened to Lydia at the end of HD1pt18?
Obviously, she lived. But you knew that. The whole story goes something like this: Katherine and Blip discover that Lydia’s passed out and about to die, and they try to help her with injections and such. When her heart stops, Katherine brings her to Earth to try something, but doesn’t do so hot. Blip, who if you’ll recall just had his battery enlarged, gives her a jolt. This brings Lydia back, and Katherine is able to save her. Blip, however, is nearly drained and has to sit and recharge for a long while.
