That's pretty confusing.  How about this:

class Class1
  attr_accessor :var2

  def initialize(aVar)
    @var = aVar
    @var2 = nil

    if @var == 1
      @var2 = 1
    elsif @var == 2
      @var2 = 2
    end
  end

end



class Class2
  attr_accessor :container1

  def initialize(container1)
    @container1 = container1
  end

end



class M_class
  attr_accessor :m_container

  def initialize
    @m_container = Class2.new(Class1.new(1) )
  end

  def set_var2=(val)
    @m_container.container1.var2 = val
  end

  def get_var2
    @m_container.container1.var2
  end

end


obj = M_class.new
obj.set_var2 = 2

puts obj.get_var2
