Doctor Who Season 2

I've finished watching Doctor Who Season 2 which is 1964/65. It's very interesting to watch and even though I shall miss them, Ian and Barbara found their way back home although 2 years into their own future (they left in 1963 and returned in 1965, I guess they couldn't go back to where they left). Poor Susan was left behind on earth in I think the 23rd or 24th century right after they defeated the Daleks. At any rate, he has 2 new companions and I can't wait to see their futher adventures in season 3 which would be 1965/66
