Nah, dont think so. Alex is hostile towards MC from the start, this is not how you introduce a Bro. I think it was planned from the start that one Crewmember would do this. And it had to be a male crewmember, because a female one would mean that there is a potential LI of the Harem who is not available even more (even if this person was never planned to be part of it at all).
Vann is a Bro-Character. Way different introduction than Alex. (But even there people were concerned, because he is the Ex of Noel)
