naw grimmjaw just got battered and and that was that really.
Ichigo will attempt to save Yoruichi from being killed by an unknown enemy. Since Ichigo is interupting Yoruichi's marrage ceramony, the soul society thinks Ichigo is now an enemy. Soifom attempts to stop Ichigo but he gets away. It's basically Ichigo trying to save lady Yoruichi from being killed due to her power as the princess.
No. Ichigo has not, yet, kissed Inoue Orihime. Orihime however, has almost kissed Ichigo, but not the other way around. In fact its suggested that Ichigo is completley oblivious to Inoue's feelings for him. However the plotline has yet to finish, so anything can happen.
Well so far in the anime, it hasn't really said that Lirin DOES like Ichigo, it is possible but then again, anything could happen, its up to the makes of the show in Japan so, meh, anything could happen...
Prior to Ichigo's birth, his mother was attacked by a hollow. Which you will find in the latest episodes reveals that others like him had the same happen to their mothers. This is turn left the hollows "reshi" behind in the womb. Thus giving Ichigo and the like hollow powers.
In the Manga or the Anime not as of yet but that dosent mean it wont ever happen
