Arcee's voice does comfort her, and Matilda looks up at her. From the sound of it, it seems like this person knows who Airachnid is. That, or she at least knows what she is and thus what she is capable of. She wonders if all Cybertronians are built and act like Airachnid.

The next question is one that she deliberates over. In truth Matilda hasn't really been having a lot of luck since she struck out on her own. She still isn't particularly keen on the idea of turning herself into any authority and risking ending up somewhere she might not want to be, but at the same time she actually feels like she's getting somewhere. She'd not ready to admit that she was actually by herself, but she will at least be forthcoming about what happened between herself and Airachnid.

"Promise not to tell anyone?"
