Mark stood next to Tracy, feeling helplessly nervous.

I have a question about this sentence.

If context is added, according to context, can the sentence mean either 1 or 2 below?

1. Mark stood next to Tracy, and Tracy felt helplessly nervous.

2. Mark stood next to Tracy, and Mark felt helplessly nervous.

I mean without context, the sentence can mean both 1 and 2?

I think so, but I'm not sure whether I'm right.
