Mr. And Mrs. B are still summoned. Yulya and Cat, please state your intentions.
Alice attempts stealth with disadvantage [1d20+1d4+5=26,19] She succeeds.
I remain hidden and wait for Alice to spring the surprise then send the kids after her with Rally speed.
[They are 100ft away, I'll make a map for round 1. Remember that surprise attack only guarantees initiative, there is no longer a surprise round and you can only gain advantage by legitimate means such as flanking and stealth.]
