cool story and it looks good so far. lion-o may be grown but he still acts like a cub sometimes. :) as for title suggestions, i can't think of any at the moment, but i'll let you know if i come up with one.
Nice work! There's noting to worry about with your portrayal of Lion-O and Kat. They came off as the teenage boys they're depicted as (Lion-O in mind at least and not body). I hope you continue this.
