Lane has come a long way over the years, and she has done very well putting up with Rory as a best friend. I admire her!! She has great honesty to herself and what she wants and believes in!!!
In the early episodes she rebelled against her mother with the music and the image but hid it, and now she has taken that passion and made it her life, with the band and all!!! The tour in the churches just shows how much she is prepared to do in order to succeed in her life!! The show used to focus on Rory's success and Chilton and Yale but now Rory is at a standstill, Lane is flourishing!!! I think its great!!!!

and BubbleTea, i think your theory sounds possible, if Kirk was to be Lane's dad (??

) Mrs. Kim has been trying to prevent Lane following in her footsteps!!
