I am confused. How can a certain look be interpreted as one of jealousy. That seems quite a leap of assumption, as you don’t know with any degree of certainty what she was really thinking - and much less what she was feeling. Might simply have been wonder at how you interacted so differently with old T.

Seems a bit strange for this new person to be that emotionally enmeshed as to feel something so strong as jealousy for a client... Especially seeing she’s seen you for such a short time.

I wouldn’t be so quick to jump to conclusions and 'condemn' her for what seems like mere mind-reading. Give her a chance or at least talk it out to be sure (i.e. confirmation coming from the horse’s mouth).
