Who damaged Dr Rolf’s Lab ?

After today’s show I think it was Dr Shah. He was acting strangely toward Jenn, not kind like he’s been in the past. His entire personality is different. Plus, the hospital took over his lab. I think they just brought him back for this lab /memory serum destruction.  Why else pop him into the show again when he doesn’t have a real story line other than Jenn’s occasional date.
