communicate more with your 99.. call your 99 to ask about ar B more often and when 印印 back home, ask her about ar B as well.... so, you know both side.
And try to get closer with 99.. and tell 99 that you depends on her to look after ar b and 印印 can't be too relied on.
if 印印 did something wrong, don't hesitate to let your 99 know. I think as long as you & 99 are on the same side, 印印 will not have a chance la.
