what Ikkaku isn't telling George:
- all about his commitment issues. Ikkaku has commitment issues, which is why he's reluctant to tell George what he knows she ought to hear. Ikkaku has not been tied down to anyone except Yumichika for several hundred years.
- the magnitude of his feelings for Rey
what Ikkaku really believes:
- that everything will be alright
- that George could have it so much better
- that George wouldn't adjust well to Soul Society and regret going there
- he's not of much use to Rey, and that he's far more attached to Rey than Rey is to him
- he's not really capable of giving people what they deserve. Notably, under ordinary circumstances this fact almost never bothers him.
- he and Yumichika aren't dependent on one another
people whose opinions he actually gives a damn about right now
- Death
- Ryuuken
- George
- Rey
- Yumichika, but to a lesser extent
- probably Cher
