Hi there! Please feel free to use this post to drop a comment or constructive criticism and I'll see what I can do to improve! Any questions in general can be brought here as well if you don't know how else to reach me. Comments are anon enabled with ip logging disabled.

backtagging/threadjacking: yes to both! no matter how late it is, I always welcome backtags.
fourthwalling: he... probably won't understand much of what you're talking about but you can try if you want. (he will get really emotional if you somehow mention eve though)
hugging/kissing/flirting: hugs are absolutely fine! kissing and flirting though... probably not
fighting: you can try fighting and injuring him, but... why would you even do that to this poor robot. same goes for killing, though that is something I'd rather talk about first before you try doing that.
mind-reading/brainwashing/hypnosis/etc.: if you have a power that works on robots and a permissions post for this then I'll fill it out! otherwise, just ask first if you're not sure about something.
triggers: I'm generally okay with anything that's IC for the character/situation. if it's something completely out of the blue then I'll generally let you know whether I'm comfortable with that or not.
