Throwing an idea out there for the sake of it, not entirely sure if it's plausible: what if Iyatil is referencing "shards" not in the general sense, but two shards in particular- two shards that might be taking up a particularly large part of Kelsier's thoughts as he plots to protect his homeworld? Two shards that, though locked in an uneasy state of stasis now may well prove to be as dangerous to Scadrial's future as they were in its past (esp. given the prospect that Sazed fails to keep them in balance and becomes Discord)? If Iyatil is after BAM for the knowledge she has on how to control the power of a shard without assuming the shard's intent completely, then it makes sense that she would be keeping this from Kelsier. It sounds like something he might want to know more about after recognizing the limitations of holding Preservation in SH, but he likely has some reticence towards moving against Sazed directly (as exhibited in his conversation with Sazed at the end of TLM). Thus, she acts in a sort of "better to seek forgiveness than permission"-type way.
