Threadhopping with this character - yes/no/it depends? Yes, I'm okay with it! Unless it's marked private or it is specifically stated that it's a closed thread such as in a log, I really don't mind at all. Have at it! Crowd Lloyd as you please!
Backtagging with this character - yes/no/it depends? Yes... and no. I guess it depends? I mean, I'm down for three or four day backdating, but if it's been a week, you're pushing it--unless it is extremely pertinent to your chaacter.
Back-dating entries with this character - yes/no/it depends? Yes! I get busy sometimes too, but I love logging, so I am a fan of backdating them.
Hugging/kissing/other sort of intimate actions with this character? Lloyd will shy away and be brusque or rude with anyone who attempts anything with little exception, but you're free to try! Perhaps something will come up to make him change his mind? You can make it a goal!
Punching or causing some other form of physical harm to this character? Lloyd's a little bitch girl so he's not really going to get into any fights, but you can do as you please to him as long as you ask permission first.
