Maybe their true forms was leaving her with fear, and would be better they used their holoform with her, only Ratchet would use this form, because he need to work in the panel and in the bridge. Bulkhead was the first.
"Why you are in your human form? I know how you are."
Bulkhead smiled to her.
"Say for me. Are you feels better if I use my human form? Miko smile and made one positive movement with her head.
Her smile made his spark to shine, Ratchet thought better the situation. Why not? He will try using his holoform to help Miko.

That afternoon, after one recon mission, Optimus, Bumblebee and Bulkhead came back and looked Ratchet in the side of Miko with her guitar.
" Look Miko, This is your favorite instrument."
Miko doesn't recognize the instrument, but Ratchet puts in her body and took her fingers trying to make any sound.
Ratchet remembered himself when Bulkhead was with the same problem, because the synthetic energon formula and Miko used the guitar sound to make him to remember who he is. Maybe this would work with her.
Miko felt herself nervous, but Ratchet was talking with calm. He was telling about when she usually makes him crazy with the noise. Miko laughs. In one moment she put her hand in her head.
"My head is hurting." She says.
Ratchet stops with he was doing and says to her to rest. Miko looks to Bulkhead.
"I would like to remember."
"Don't worry Miko. With the time you will remember"

Every time when were possible, they leave their true forms, and uses the holofemas. The Mechs forms were in one corner of the base in vehicle model to not scare anybody, in one hope to help her in her memories.
"I had one idea." Said Bulkhead. He goes to his true form, and opened his door. "Come in Miko. Maybe this will help you."
"What do you will do?" Ratchet asked worried. "Take her in one familiar place. Just this."
Ratchet turned to Optimus waiting any disapprobation, but he doesn't say anything.
Bulkhead needed to stay one moment alone with Miko, would be impossible she not feel anything, but now Miko was most accessible, and Bulkhead would try to talk with her.
Bulkhead needed to stay one moment alone with Miko, would be impossible she not feel anything, but now Miko was most accessible, and Bulkhead would try to talk with her.

Bulkhead went with Miko to a place where was possible see a beautiful view. At the site he asked to stay in his true form, and there put he in his shoulder, in a position that could see a beautiful view. There he started talk with her about such thing what they lived together. When she and Wheeljack went catch Hardshell; after This Decepticon leave him between the life and the dead, and Miko alone killed him.
"Do you know that until Megatron has doubt about your fragility?" Bulkhead gave laughs.

Bulkhead was pulled memories in his processor, and noticed that Miko was making her part; trying to remember, but something plays they to the ground. Miko rolled and stopped in one stone. Bulkhead saw Breakdown and Knockout coming. He knew that this would not good thing.
