Welcome little one! (Transformers Prime)

Mikayla lives alone due to the fact M.E.C.H killed both of her parents. She was almost killed but luckily, Optimus Prime found her before they could do anything more. She became Bumblebee's charge and he protected the sparkling.

Mikayla has become close to the Prime. He doesn't want to admit it, but the child has grown on him and he feels happy every time she is in his presence. Agent Fowler knows about her and there is only one problem: She has a very bad heart.

What will happen when Mikayla has a bad heart attack and it almost kills her?
