Im sorry if you've already talked about this but how do you expect the team to react to Shiro's disappearance ? :o I think Keith's reaction will be interesting if you consider his fear of abandonment
I think that honestly a lot of speculation on the team’s reaction hinges on them like.. immediately understanding/accepting that Shiro’s disappearance is a permanent or at least a long-term thing and rather than doing everything to try and find Shiro they need to focus first on being able to hold their positions.
It ignores the idea of the team panicking- which, they would, and all in their separate ways- and the amount of unknowns in the situation. It hit them out of nowhere like a sledgehammer, and I feel like fanworks do a bit of a disservice by not picking up right at that point of impact or shortly afterwards.
