The Walking Dead buy all episodes of season 1 or buy episode 1 of season two?

I only have 5.90. Episodes in season one are for sale and I already have episode 1 and 2. Season 2 episode 1 is 5$. The ending for season one Is spoiled so I don't know if its worth buying all the episodes for season 1. But season two is only 1 episode and I already watched playthroughs of it till she goes inside the home(don't wanna spoil more) which one should I buy?
