I would say this is a bad idea, since I believe Thread is a core
class.  Call it MyThread, or ThreadDesc or something else.

Get rid of all the semicolons; they are usually not needed.

toS is not an existing method, but to_s is. Use that, or do this which
is more compact:

def filename
   "./data/#{@number}-#{@replies}.html"
end

Couple things here:
1. return is not necessary, as functions return the last evaluation.
2. #{ ... } within a string evaluates what is inside the curlies, and
embeds that in the string.

You'll need to create the array first:
    thread = []
or
    thread = Array.new
