Daniels said that in the original timeline the Xindi never attacked Earth. So what does the original timeline look like for the Enterprise crew? Archer's ethics were never stretched to the breaking point. T'Pol got Pa'nar syndrome but never struggled with Trellium-D addiction and Trip never needed Vulcan Neuropressure so they most likely never had a reason to get to know each other better. T'Pol probably stayed much more like she is in seasons 1 & 2. Presumably even Storm Front didn't happen.
What else is different in the original timeline?
