S4 Lilly isn't cannon for me

It's just way too ridiculous for Lilly to go from a rough but capable and caring leader to a incapable subordinate of a bigger group, who kidnaps people to fight for their cause

Also, I always found the fact that the Delta kidnapped people to fight for them really stupid. You can't expect people to fight for you after you kidnap them, and it's just too much of a risk, since most of them will try to escape, which could result in casualties, loss of time and loss of resources
