honestly, i think one of megan's biggest friction points with the rest of amber's unit is that she's too focused on keeping amber happy, and doesn't care enough about the rest of the unit members?
like, i'm specifically thinking about a part in borderline where they had a team leader meeting right after a run, and amber says something about they usually don't have snacks during their meetings. megan replies that they usually don't have meetings right after runs, and that amber hadn't eaten anything since that morning.
amber notes, but doesn't say out loud, that no one else had eaten yet either, but that megan doesn't care about that.
and that just illustrates a big part of the problem, right?
adika has mentioned at many points that amber is "too indulgent" of her unit members. she goes out of her way as much as she can to make things easier for them - she tells rafael and zak about the opening on beta team, she invites matias' teen level girlfriend to be part of their unit, she makes sure to specify that she wants nicole's new deputy to not have the team leader imprint so there's no risk of them challenging nicole's authority.
a good senior administrator would recognize that caring for the whole unit would be the best way to care for amber and keep her happy. because the happiness of her unit is one of amber's priorities.
obviously, there are times where she is thoughtful of others - like the way she emotionally supported emili after the fire in defender, and how she jumped in to help beckett after he was kicked out of keith's unit, and those have been the times where i as a reader and amber as the protag/narrator have liked megan the most. but those times are few and far between.
it's a stark contrast to the other team leaders. as hard as adika is on his strike team, he's very protective of them too (when they're discussing bringing new members into the unit, and he says that he's not accepting any of morton's men as temporary strike team members because it would be damaging to the self esteem of his greenies), and he's always sure to publicly praise them when they do something well.
and of course lucas's friendships with his tactical team members is very evident in the good-natured way he accepts ribbing from them, and even when buzz was annoyed at him for making forge blonde to infiltrate teen level during the whole blue upway thing, lucas accepts it all with good grace.
meanwhile, megan's relationship with amber and the rest of the unit keeps fraying, especially with buzz having to call her out during new year.
i can't help but wonder if this is all building up to her finally leaving the unit in book 6
