In Beta world line, wasn't John Titor supposed to appear in 2001?
But now, we find Amane Suzuha in 2010, calling Okarin to help her preventing WW3.
Time Machine supposedly can only travel back in time, that's why Suzuha decided to visit 2010 to find her father before going to 1975 in Alpha world line.
Assuming we're now in the same world line as the first episode (probably with minor deviation in divergence number), I guess Suzuha traveled back to 2010 first to warn Okarin about the WW3, then went to 2001 to do something which is most likely related to WW3?
