Okay, Luke, you've got to stop saying stuff like "Christian and I's team". You're a smart guy, and you're trying to use the correct grammar in a situation where people usually make a mistake. The rule is, you use the pronoun that would be used if not including another party. So it's "Christian and my" team. You wouldn't say "I's team", so you wouldn't say "Christian and I's team". Lets get things straight Mr. writer guy.
