Yeah, he's alive.. will be back badly injured.
Pete ends up confessing his part on his injuries as everyone blaming cain and ross tells it was pete. Debbie wants pete out of course, james begging her to give pete bit more time.. And Emma is needed to nurse ross back to health and look after moses.. And so on.. Nothing in those spoilers suggest that ross would be dead. In fact - if Ross was killed by Pete and Pete confessed, surely he'd be arrested straight away?
