Well... I must say that WildBill and I were probably the Lennus2 experts. Note that I used the past tense... I really wish that I could give you the intel you're seeking, but honestly, it has been SO long since I have played the game that I have mostly forgotten the little details. I don't think I even ever noticed Melina not being in the ending. I'd need to test it out again to see if I can find her. Maybe you'll get lucky, and someone else will see this post and be able to answer your questions
